Hey there, nice tutorial! Just wanted to add that if you want sharp corners just put a "Ceil" node between the "Subtract" and "Lerp" nodes, to round off the float that comes out of the gradient to the nearest integer. You will have to decrease the sharpness to a low number, though - something like "0.1".
The problem with using UV to detect edges is that this outline will only be uniform with uniform UV like a cube. For a rectangle, some edges will be thiner than others
Hey Watulio, I use Unity5 but don't have ShaderForge. Is there a way to export the Shader code so I can use this in my Unity projects? I really like this material effect and can't seem to find an equivalent tutorial to this using Unity.
Hey Watulio, now that Shadergraph is build into Unity 2018, do you think you can re-create this using Shadergraph so I can see how it should be done. I'm playing around with it now but just can't get it right so far.
Thanks for doing this, is a lot easier this way then the way you did before haha. edited the rest of the comment out figured out my problem. But still, awesome tutorial hope to see more from you! :D
wow, It's a lot to learn but that was fantastic, If the laser show software I use exepts the format perception neuron in Glow matirial style. this will be amazing but I would just use lines with no shading because as you know laser displays look the same as glow style graphics :)
This was cool. Thank you. And it does work on a sphere. If you change the edge it almost looks like a sideways creature opening its eye. I may have another use for this. :D
That would be a problem with the rendering configuration or scalability settings, I believe. Make sure you are not on low settings or mobile rendering, IIRC that's where the bloom is disabled.
Any chance you can show us how that would work? I have tried unwrapping by polygon, unwrapping it by angle and using material id's. Nothing seems to work - the glow seems to appear randomly.
everkaaik Yeah, that tutorial is long due. I am still trying to find time to make it, sorry :( I used Maya to unwrap the UVs based on the glowing rectangle I made up in Photoshop - which simulates the way this material applies on the mesh.
Yeah. I tried unwrapping by polygon too, doesn't work. I just want it to work on edges. Something tells me you used overlapping UVs which isn't a good idea.
@@Mewbits technically he would have, but when you import a model with overlapping UVs, Unreal auto generates an alternate UV map for lighting data. To check on this, you can find it when inspecting your model in Unreal. (you may also want to change the light map resolution to be appropriate for the size, scale and importance of your model)
I need help, i want to change the material of the base, like the black part, I want to change it to more metallic and shiny , how can I do that? pls help
Does this work with more complex shapes and can you limit the minimum angle of the edge to which emission is added? Basically what i'm asking is could i use the same principles for making an edge highlight for a low poly rock material?
Thank you for the tutorial. Is this material suitable for non geometric shapes? If I wanted a character to have similar effects going on would this work or would I have to create a more traditional material?
Hi, I was wondering if you could possibly add to this tutorial to cover custom meshes. Also, if I begin a new level in unreal and try to map this material to the 'floor' of the level it doesn't work, it instead glows completely all over really brightly, any ideas?
euden Hi, New level uses the BSP geometry, which has completely different UV mapping than the cube. Using custom meshes with this material is as simple as making proper UV maps in the modeling/sculpting software. I can't promise any tutorial on this topic soon, sorry, I am stuck with tons of work :(
How could you change this to become like a grid? So it divides the cube shape up rather then just lights the edges? I know nothing about materials so forgive me if thats a ridiculous question
+TheMalibuLizard it's a good question, I actually needed this functionality myself. You only need to add couple of nodes, I believe I covered it in the last tutorial about tron material on my channel. Check it out, and write me if you'll have any more questions :)
I took the texture coordinate. changed settings on everything to make it tiled. and that worked great. But I'm also trying to make the black surface completely see through so I can add multiple layers of the glowing grid but cannot seem to do this without making the light up sections invisible too. any suggestions.
+Liaret lol. that was easy. Thanks for the reply. it looks good and good job on tutorial. one thing. please talk a little slower on tutorial. hard to read inputs on screen. other than that thanks very much.
hmmm sure, good idea. I think you'll just need to use some noise or otherwise interesting texture to blend wear textures into the material, but that should work. Let me know how it goes!
QUESTION!!! Can you use a gray scale map to show Unreal which parts of an object are more shiny than other parts of the object? Like say you have a metal gun with rust on the side. The metal on the gun would be more metallic then the rust which would affect the amount of reflection that comes off of the mesh?
+Jarhead Junior sure you can, that's a part of PBR rendering pipeline. Just connect the map to the Roughness (and possibly specular, depending on the effect you wanna achieve), and make sure the map has whites for the most matte surfaces and blacks for the most reflective ones. However, this is only the roughness - if you also want to simulate metal surface, you will need to create a metallic map and connect it to Metallic channel. Same idea, but metallic works "physically correctly" only with 0 or 1 values (0 = non-metallic, 1 = metallic). You may find more info on Unreal docs pages.
The material? When you save it, it compiles. If it still looks like default grey material, pls look around for compile errors. They r usually on the bottom of the editor.
And now, to guess how to apply it to the borders of a single plane... Thanks for sharing the method for cubes though. Nevermind, I found out by pluggin in a INVERSE TRANSFORM MATRIX between the last MULTIPLY and EMISSIVE COLOR can extrapolate the shiny edges to a single plane. Let's fiddle more...
where do you pull up the texture coordinate? every time I try I just can't find it. I have never used unreal before, my instructor told us to try based on this video. I don't even know what I am doing. PLEASE HELP.
Wow, I already got instructors pointing out my videos, neat :) Right-click in the material editor to bring up the node selection pop-up. There are lots of nodes, so you wanna filter them by writing e.g. "texturecoord" While you are doing that, it would filter nodes until you see "TextureCoordinate" node in the list. Then just click on it to place on the graph.
+Liaret This tutorial is amazing and I love what you've done with it. I read the above comment (on how to make he center of the cube transparent) and would love to do the same but am not clear on your instructions. Would you mind elaborating some on that? Thanks :D
David Henry sure. Basically you take the whole thing where we procedurally generate edges and end up with square-like texture and use it as an opacity mask. This way the only non-transparent things will be the edges (what we need). Afterwards you can plug any color into base or emissive inputs, which would paint those edges. I can make screenshots for you if you need more info.
Thanks so much for the great tutorials on this. Just a quick question, I'm using this material tiled on a floor, using the method Sebastian S posted here in the comments. And I'm noticing a lot of aliasing artifacts.. Is there a way to fix or reduce that? I'm pretty new to UE4, so I could have missed something simple..
+NikoKun My pleasure. Now, I have faced aliasing issues as well. Without going into some kind of post process fix, I'd just suggest you use thicker glow lines. The aliasing appears when the line on your screen is thinner than 1 px, essentially. This should be fixable with anisotropic filtering, so you can dig into that as well.
+Liaret Ah ok, thnx for the quick reply. I'll see if thicker lines will help.. I tried to up the AA, but that just made the grid areas in diagonal directions that were farther away from the player disappear completely to black. Is the anisotropic filtering options part of the post processing stuff? Cause I didn't notice it in the normal graphics settings.. :/ Guess I finally need to start learning how PP works.. heh
+Liaret hmm, So theoretically, if I use your original Tron material, which used that gradient texture, I could take advantage of anisotropic filtering? (not even sure if that would actually help fix the problem tho, plus I'd have to figure out how to tile that one. heh) For now I'll just mess around with thickness and see if there's anything I can do with PP, but at least it's another idea. ;)
Hi, first of all, many thanks for your tutorials - they are very helpful!! Could you do a tutorial on holographic shaders please? As there are no good tutorials abot that on the net? Thank you in advance!!
I followed your instructions exactly but I got nothing on my cube. Would it be possible for you to upload the material files for the community to use and study?
Timothy Dilich hey there. Here's the archive with the materials. Let me know if it works or if you need my folder structure (cause uassets are kinda strange in this matter). dl.dropboxusercontent.com/u/48256366/TronGlowMaterials.rar
This is great, i'm trying to get a grid effect for my floor like in your previous tron material videos but not had much luck. How do you create this effect?
Hi, here's a screen of my old material's grid. I have not thought about implementing the grid in the new material as of yet. There r some useless nodes here, like two-color switching, so don't mind them. The texture I use can be found in the sample content s018.radikal.ru/i511/1503/1e/25e9cafbef69.png
Liaret you can multiply and frac directly after the texCoord before it goes into the multiply*0.5 to get a grid effect. you could also save one instruction by using an add instead of a lerp and make it less busy with less branching. dl.dropboxusercontent.com/u/107682595/Random/Tron.png nice material and great that you have forgone the textures. :D
I don't know if you still are looking for an answer to this but I accidentally managed to achieve this effect by reducing the "Glow Strength" parameter a lot (around -100)
Hey Liaret, Firstly 'Happy Friday' to you! Thank you so much for the most cool tutorial, thoroughly enjoyed doing it. After following it with every detail, I have one small problem whereby the edges do not glow, they just remain dull. I have tweaked the scalar parameter values, however, there's no radiance at all. I downloaded your materials also and the same, they appear dull. Would you have any pointers as to why this would be please?
Dominic Brown Hi Dominic, Thanks, Happy Friday to you too :) It appears that the radiance (or even bloom) is disabled in your engine's settings. Please check out the scalability and rendering parameters in editor settings and project settings.
Nice one, thank you for getting back to me. Under Project Settings>Engine Rendering>Default Processing Settings, Bloom is on. This location was the only place I could find any reference to Bloom. As opposed to working on my existing project, I transferred the files to a new project and they display ok, thank you. Those settings are like a minefield, lol. Thank you again. Enjoy the weekend =]
Hi, I'm new to UE4 and I followed your steps and created the material and it works good on a cube. But I have a more complex shape, a maze I did in Maya, and just a couple of edges are glowing. Is there a way to tweak this material so that the edges of my maze are glowing? Or do I have to create a alpha map for the edges?
Johnny Blaze Hi there. I also work in Maya and faced the same problem with complex geometry. You have 2 choices: - Make custom materials for each model with unique UVs - Use one material, like this one from the tutorial, and make custom UVs for it in Maya's UV editor. I went with the second approach, cause I knew I will only use those meshes with my glowing material. It is also theoretically cheap, cause you might have a lot of meshes on map using the same material (but different material instances, for example). So I faked the material in Photoshop for a reference, put it into Maya and now I make custom UV maps for my meshes which fit this material. Albeit, it does not work well with complex geometry, but that is to be expected. I can provide some screenshots to make it clear, if you need more guidance :)
Kevin Martinez which blueprints? There are no blueprints involved in the process. I will try to find time for a tutorial, but can't promise any dates for now :(
Liaret I want to create a maze with edges glowing, but i dont understand the part " make custom UVs in mayas UV editor" how that "texture map" will looks like? just highlighting the edge parts on the maya UV texture editor and then change de TexCoor node for my custom texture UV on Unreal engine?
Kevin Martinez ok, first of all, this is a tron material mock I made in Photoshop. It simulates the material which is created in the tutorial. You can assign it to your mesh in Maya and then carry around the UV shells in UV editor in the way that the edges you need to be glowing are glowing. I have attached another screenshot for example, where I am mapping round shape's edge to the glow material. dl.dropboxusercontent.com/u/48256366/TronMatMock.bmp dl.dropboxusercontent.com/u/48256366/MayaTronExample.PNG
Hey Liaret! Nice Tutorial, thanks! I'm trying to get this shader to work with custom meshes, shapes that are better than plain cubes. But not having much luck. It works on primitives, but not custom meshes. Any idea why? THanks!
@EJtheArtist Could you expand on that solution? I don't quite understand what youre saying. I made a couple of geometry brushes and then converted them to static meshes and I am running into the issue of them glowing super bright. I can't seem to find anything about "stretching to 0-1 space and overlapping". Could you help me please?
llamadoH Gaming do an automatic mapping on your object, and then try moving the uvs closer or further away from each other in the uvs editor. If this is not clear enough message me on my channel and I'll make a quick video
Hey there Liaret, dont know if you're still gonna reply on this video.. But. I followed this step by step numerous times now and I cant get the Glow to emit off of the material, as shown in this video. As I say I've followed this numerous times, and I recall having it set up properly at one stage but I seem to have changed something in my project settings.. Bloom is on, any ideas?
Слушай, а подскажи насчет glow эффекта. У меня в проектах при установке эмиссив больше единицы glow эффект не возникает. Более того - если взять материал с рабочим glow из примеров и сделать миграцию этого материала в рабочий проект - glow эффект исчезает. Соотвественно и после этого туториала материал создается правильно, но glow эффекта нет. Может требуется где то в настройках проекта указать что-то?
Denis Blagodarev у тебя в настройках, вероятно, выключен блум. Особенно это характерно для мобильных настроек качества. Если слабый комп, анрил мой сам занизить качество. Покопайся в настройках рендера.
Is this broken in 4.7.6? the material preview is correct, but when I apply the material, the entire screen becomes filled with the color of the the vector parameter.
egotisticcougar You are applying it to BSP geometry. On BSP, it would only work when set to fit, as it is a procedurally generated material. To make it work as a grid, you can use a hint from Sebastian S here in comments (please scroll down to find his comment).
Followed this tutorial but my glowing material is bright white with a colored glow around the edge instead of a fully saturated glow like in the vid. Any thoughts on what's going wrong?
Not sure what to double-check or how (pretty novice when it comes to this engine). I posted my materials on the UE forums here: tinyurl . com / kt6rszv
According to the UE forums, the issue is that the engine was changed to render emissive glows in a different way. So far there is no way to achieve the type of lighting shown in this video with the engine the way it is.
I ran into a problem with the material. I applied everything that was stated in the video but I attached it to emissive a warning from stats says that arithmetic between floats is undefined. How can I fix this?
TheLuisberg Top Commentor You have probably made some invalid node connections. You can post here a screenshot with ur code so I'd try and see an error.
Hey its me again I figured out what the problem was. It was with the masks g and r. I had them mixed up. Everything is fine now. But when I apply the texture to geometry or some solids and stuff. Everything goes white. It could because of the starter Map I'm on but I need help on that
+hasher22 please check if you even have the Bloom enabled in the rendering settings. Then add the postproc volume on the map and pump up a bloom on it to see if it works.
Liaret put this mat on a tri-pyramid in the editor, im trying to get it to create the edge effect on the mesh but it doesn't work, it might be messy lol im only 14
nolan mckaun it's all about UV-mapping. To expect the desired effect you should get the mesh into Maya/3d Max/MODO etc and make a proper UV map, matching the material.
This is very nice and helpful tutorial. I am going to use this tutoorial to make tron material for my college project :] (Rocket_Jumper) I gave credits to you as the author of the reference just incase. Nice work!
You don't have HDR enabled, if that's the case. Try checking Mobile HDR in the options. There should be some other settings controlling that as well, look around the documentation.
Hey there, nice tutorial! Just wanted to add that if you want sharp corners just put a "Ceil" node between the "Subtract" and "Lerp" nodes, to round off the float that comes out of the gradient to the nearest integer. You will have to decrease the sharpness to a low number, though - something like "0.1".
Just what I needed. Thanks :)
Ceil?
Ceil?
I have used this tutorial multiple times and I come back because you explain so well and simply
The problem with using UV to detect edges is that this outline will only be uniform with uniform UV like a cube. For a rectangle, some edges will be thiner than others
This is really cool! Thanks a lot for this tutorial. I've been using your original tron material in my project.
Awesome! Still useful to me today, thank you. :)
Pretty good tutorial. With a few adjustments it worked for ShaderForge in unity
Hey Watulio, I use Unity5 but don't have ShaderForge. Is there a way to export the Shader code so I can use this in my Unity projects? I really like this material effect and can't seem to find an equivalent tutorial to this using Unity.
Try rebuilding it in substance designer, i guess
Hey Watulio, now that Shadergraph is build into Unity 2018, do you think you can re-create this using Shadergraph so I can see how it should be done. I'm playing around with it now but just can't get it right so far.
Thanks man for an awesome tutorial!! Easy to follow along with, nice job!
This looks better, and a lot smaller too, thx for sharing.
Thanks for doing this, is a lot easier this way then the way you did before haha. edited the rest of the comment out figured out my problem. But still, awesome tutorial hope to see more from you! :D
Thanks for sharing! I actually followed along in Unity using Amplify Shader :) almost identical
Dude, thanks a lot! I knew there was a way of doing this with only instructions but never knew how to actually do it, until this video haha
My pleasure :)
is there anyway to make this work for more than just cubes?
Great video, was a great help.
wow, It's a lot to learn but that was fantastic, If the laser show software I use exepts the format perception neuron in Glow matirial style. this will be amazing but I would just use lines with no shading because as you know laser displays look the same as glow style graphics :)
8:57 I think "Max" node could help with that
This was cool. Thank you. And it does work on a sphere. If you change the edge it almost looks like a sideways creature opening its eye. I may have another use for this. :D
I didn't hear a few steps but it works for me...except mine doesn't GLOW like yours does...it's just a lighter tone of the color i choose
That would be a problem with the rendering configuration or scalability settings, I believe. Make sure you are not on low settings or mobile rendering, IIRC that's where the bloom is disabled.
The problem about this material is that it will only work on box
No, not really. It works on whichever mesh you UV-map for it.

+Jarhead Junior keep in mind that you can use Substance plugin for Unreal, which will simplify the workflow and let you tweak substances in UE4.
Liaret That's for substance designer and I haven't found any tutorials that teach it well enough. Substance Painter just exports maps.
+Jarhead Junior right, my bad :)
How do you compile it? There's no option in the blueprint as it still appears like a default material.

Thanks
+Liberula1000 hi, I didn't quite get what do you mean. Could you be more specific or provide an example? :)
+Liaret Let's say I have two colors and I want them to alternate with an fade in/out effect

Liaret you can multiply and frac directly after the texCoord before it goes into the multiply*0.5 to get a grid effect. you could also save one instruction by using an add instead of a lerp and make it less busy with less branching.

nice material and great that you have forgone the textures. :D
Sebastian S perfect, thanks for the insight :-) I was never good at math ;)
Do you still have the blueprint for this? Your dropbox link doesn't work
I'm curious, does someone know how to do the opposite, meaning a white/colored box with black edges, like this ?
I don't know if you still are looking for an answer to this but I accidentally managed to achieve this effect by reducing the "Glow Strength" parameter a lot (around -100)
Hey Liaret,
Firstly 'Happy Friday' to you!
Thank you so much for the most cool tutorial, thoroughly enjoyed doing it.
After following it with every detail, I have one small problem whereby the edges do not glow, they just remain dull. I have tweaked the scalar parameter values, however, there's no radiance at all.
I downloaded your materials also and the same, they appear dull. Would you have any pointers as to why this would be please?
Dominic Brown Hi Dominic,
Thanks, Happy Friday to you too :)
It appears that the radiance (or even bloom) is disabled in your engine's settings. Please check out the scalability and rendering parameters in editor settings and project settings.
Nice one, thank you for getting back to me.
Under Project Settings>Engine Rendering>Default Processing Settings, Bloom is on.
This location was the only place I could find any reference to Bloom.
As opposed to working on my existing project, I transferred the files to a new project and they display ok, thank you.
Those settings are like a minefield, lol.
Thank you again.
Enjoy the weekend =]
Dominic Brown no problem, you too :)
Hi, I'm new to UE4 and I followed your steps and created the material and it works good on a cube. But I have a more complex shape, a maze I did in Maya, and just a couple of edges are glowing. Is there a way to tweak this material so that the edges of my maze are glowing? Or do I have to create a alpha map for the edges?
Johnny Blaze Hi there. I also work in Maya and faced the same problem with complex geometry. You have 2 choices:
- Make custom materials for each model with unique UVs
- Use one material, like this one from the tutorial, and make custom UVs for it in Maya's UV editor.
I went with the second approach, cause I knew I will only use those meshes with my glowing material. It is also theoretically cheap, cause you might have a lot of meshes on map using the same material (but different material instances, for example). So I faked the material in Photoshop for a reference, put it into Maya and now I make custom UV maps for my meshes which fit this material. Albeit, it does not work well with complex geometry, but that is to be expected.
I can provide some screenshots to make it clear, if you need more guidance :)
Liaret Can you make a tutorial of this? or just post the Blueprints here, i know its kinda basic stuff but im learning material scripting
Kevin Martinez which blueprints? There are no blueprints involved in the process. I will try to find time for a tutorial, but can't promise any dates for now :(
Liaret I want to create a maze with edges glowing, but i dont understand the part " make custom UVs in mayas UV editor" how that "texture map" will looks like? just highlighting the edge parts on the maya UV texture editor and then change de TexCoor node for my custom texture UV on Unreal engine?
Kevin Martinez ok, first of all, this is a tron material mock I made in Photoshop. It simulates the material which is created in the tutorial. You can assign it to your mesh in Maya and then carry around the UV shells in UV editor in the way that the edges you need to be glowing are glowing. I have attached another screenshot for example, where I am mapping round shape's edge to the glow material.

Hey Liaret! Nice Tutorial, thanks! I'm trying to get this shader to work with custom meshes, shapes that are better than plain cubes. But not having much luck. It works on primitives, but not custom meshes. Any idea why? THanks!
Nevermind! Got it! Each polygon needs to be stretched to 0-1 space and overlapping like the primitives! Thanks!!!
@EJtheArtist Could you expand on that solution? I don't quite understand what youre saying. I made a couple of geometry brushes and then converted them to static meshes and I am running into the issue of them glowing super bright. I can't seem to find anything about "stretching to 0-1 space and overlapping". Could you help me please?
llamadoH Gaming do an automatic mapping on your object, and then try moving the uvs closer or further away from each other in the uvs editor. If this is not clear enough message me on my channel and I'll make a quick video
Hey there Liaret, dont know if you're still gonna reply on this video.. But. I followed this step by step numerous times now and I cant get the Glow to emit off of the material, as shown in this video. As I say I've followed this numerous times, and I recall having it set up properly at one stage but I seem to have changed something in my project settings..
Bloom is on, any ideas?
Image for context... imgur.com/a/FOczi
fixed it, needed Mobile HDR and Bloom, then a restart of UE4
I am having the same issue but I already have both of these options enabled.
Слушай, а подскажи насчет glow эффекта. У меня в проектах при установке эмиссив больше единицы glow эффект не возникает. Более того - если взять материал с рабочим glow из примеров и сделать миграцию этого материала в рабочий проект - glow эффект исчезает. Соотвественно и после этого туториала материал создается правильно, но glow эффекта нет.
Может требуется где то в настройках проекта указать что-то?
Denis Blagodarev у тебя в настройках, вероятно, выключен блум. Особенно это характерно для мобильных настроек качества. Если слабый комп, анрил мой сам занизить качество. Покопайся в настройках рендера.
Is this broken in 4.7.6? the material preview is correct, but when I apply the material, the entire screen becomes filled with the color of the the vector parameter.
egotisticcougar Additionally, if I the material is set to fit this doesn't occur, but I'd like to align default like a grid.
egotisticcougar You are applying it to BSP geometry. On BSP, it would only work when set to fit, as it is a procedurally generated material.
To make it work as a grid, you can use a hint from Sebastian S here in comments (please scroll down to find his comment).
+Liaret so if I set it to "set to fit" it'll apply properly to a BSP? that's great news then.
+Liaret So, how do I set it to fit? can't seem to figure it out D:
Dzshiftt in bsp properties, there is a setting for that (Details tab).
Followed this tutorial but my glowing material is bright white with a colored glow around the edge instead of a fully saturated glow like in the vid. Any thoughts on what's going wrong?
Hello. Double-check the code, if still can't find mistake - link the screenshot to your material or share it as an asset.
Not sure what to double-check or how (pretty novice when it comes to this engine). I posted my materials on the UE forums here:
tinyurl . com / kt6rszv
Do you find why it was not working ? Because I have the same problem
Screenshot of my material here : imgur.com/a/3RdWj
According to the UE forums, the issue is that the engine was changed to render emissive glows in a different way. So far there is no way to achieve the type of lighting shown in this video with the engine the way it is.
so I was thinkin' about it, I can't access the program at the moment, but can one turn the black to white on the material?
+Dzshiftt sure thing. E.g. you set the Base Color to all white, or LERP between the edges glow color and white.
+Liaret right right right, thank you, might post a screenshot later
+Liaret Not too great at this, can you run it by me where to put that lerp? :D
+Liaret never mind I set the base color ^-^
Hi, any chance of how to make a grid floor with this effect?
Hi,
I believe there is a tutorial for the grid version of this material on my channel :)
ive gone through all the videos but i cant find it? tried myself but i cant figure it out. please help (your the best lol)
ah ive found it! thanks
I ran into a problem with the material. I applied everything that was stated in the video but I attached it to emissive a warning from stats says that arithmetic between floats is undefined. How can I fix this?
Btw the warning tag appeared in one if the Multiply node before the glow scalar and the emissive plug
TheLuisberg Top Commentor You have probably made some invalid node connections. You can post here a screenshot with ur code so I'd try and see an error.
give about a day to post it ill see if i missed anything
Hey its me again I figured out what the problem was. It was with the masks g and r. I had them mixed up. Everything is fine now. But when I apply the texture to geometry or some solids and stuff. Everything goes white. It could because of the starter Map I'm on but I need help on that
TheLuisberg Top Commentor does it work well on cubes? This sounds like uv mapping problem.
Very Awesome!
Cool tutorial!
Извини за беспокойство, можешь подсказать как применить такой эффект на объект, чтобы выглядело как сетка?
Прива. У меня есть видео про добавление сетки в этот материал на канале.
thank, I am learned someting new, nice tutorial
I followed the tutorial exactly and mine is now glowing, went through the tutorial three times and I dont knwo whats wrong :(
+hasher22 please check if you even have the Bloom enabled in the rendering settings. Then add the postproc volume on the map and pump up a bloom on it to see if it works.
can you help me apply this to a polygon?
it doesnt work the way i want it too
nolan mckaun hi. Which mesh are you using?
Liaret put this mat on a tri-pyramid in the editor, im trying to get it to create the edge effect on the mesh but it doesn't work, it might be messy lol im only 14
nolan mckaun it's all about UV-mapping. To expect the desired effect you should get the mesh into Maya/3d Max/MODO etc and make a proper UV map, matching the material.
Liaret how would one go about doing that?
nolan mckaun do you have any modeling software at your disposal?
A.M.A.Z.I.N.G
any idea if this will work on mobile ?
djbanizza will work if you use Mobile HDR, but the bloom won't be that good ofc.
Liaret Thanks mate , I'll give it a go.
Strange. I follow your tutorial with Unreal 4.15 and got 565 instructions lightning! And the result does not look nearly as good as yours
Thanks so much man :D helped me heaps :D
Xblivior my pleasure :)
Does not work on instanciated material, scale is wrong..
This is very nice and helpful tutorial. I am going to use this tutoorial to make tron material for my college project :] (Rocket_Jumper) I gave credits to you as the author of the reference just incase. Nice work!
My pleasure. Glad I could help :-)
Thx guy ! but he don't work i have this message "[SM5] (Node Multiply) Arithmetic between types float2 and float3 are undefined" :(
Check first part where he added masks. You need to select only channels he selected. Don't leave default selected channels
how to make it black?
Make what black?
Mine isn't glowing
You don't have HDR enabled, if that's the case. Try checking Mobile HDR in the options. There should be some other settings controlling that as well, look around the documentation.
Liaret
I have HDR Enabled.
and also everything is very pixelated when I go a bit away from the cube. I have AA on as well.
Could you provide some screenshots of the issues?
Liaret how?
dropbox, google drive, any file sharing hosting, imgur, etc, etc
is this cel materil?
***** excuse me?
I can't hear the nods name
Sorry. Can you see them on the screen though? :)
Yes, great video though...
very good
Thank you.
Thank you!
Thanks a lot
Thanks man
you sound like elon musk
the channel photo 😲😑😑😑😑
nice
on cube work any technology. lol shit
