Stunning stuff. Just what i've been looking for. There are channels with hundreds of thousands of subs with pure shit giving no knowledge. Im grateful to you sir, good videos, good series. Keep it on.

Thanks a lot for this tutorial Ben. In order to add even more randomization, I multiplied the time (exposed in function) with 3 different values. From 0.75 to 1.0.
I knew subscribing to this channel was a good idea. Ben you have the best UE4 material videos on the Internet! I'd love to see adding foam in the next video!
You have fantastic in depth tutorials, I am following these and others to learn UE5 materials. However in UE5, World Displacement is missing. I can do the tesselation part in Blender, or even with UE5 modeling tools. What is the alternative for World Displacement?
Don't forget to "Set Preview Value as Default" as True in the Properties of the Input nodes of the Material Function! Otherwise you'll get an error in the main water material.
I'm not much into guessing. I don't know what it is - so I'm waiting for more information. I REALLY like the idea that they're looking for ways to get rid of all of the extra stuff that artists have to do in order to get their work into the game. Not having to bake lighting, make LODs and normal maps, etc, is going to go a long way to free up artists to make better art instead of spending so much time on all of the tricks we have to do to make things work.

Hey there! First off, great tutorials, I'm a huge fan, and very happy for everything you consistently put out! I'm was going through this tutorial and I realized that there is a minor change which I might need to do: I'm assuming that there should be a way to "backpropagate" the sampling position used in the cossine term (the one which generates the vertical offset), such that my vertices only move vertically, right? If so, would you happen to know how would I go about doing that? Because I'm trying to both generate a mathematical model for the "ocean" in my game, where a boat will react to the water level with buyoancy physics as well as have the mesh which represents the wave follow the given mathematical model - essentially, I want to synchronize the heightmap which the water generates AFTER the vertex shading to an "invisible" mesh collider for my boat to float on top of. I naively assumed that it would be possible to just sample each individual wave back by an amount of "offsetSize * waveDirection", but it seems to give me incorrect results.
What are the odds that 5 months later I'm revisiting my Gerstner waves and you released this tut 2 days ago lol great info! If you could do some foam math that would be great! thanks in advance!
Excellent tutorial. I found the Gerstner Waves smoothed the ripples out somewhat, so swapped the last BlendAngleCorrectedNormals inputs which kind of sorted it out. Is there a better way?
Hi Ben, I've been looking online and I can't find any help with one thing: Once you make this ocean material and add it to a plane, how can you then make an ocean out of it? I have a very vast ocean and I want to add this material to my plane, but i need to scale the plane 100,000 by X and Y. The result is that even with a tesselation multiplier of 40, the 4000 triangle original plane just simply cannot handle the size. Furthermore, if I duplicate the plane and then try to tile the planes to make an ocean, the waves do not line up and the seams look horrible. What is your method of making a vast ocean once you have a very nice and complex ocean material?
That's a good question. My tutorial series here is focused on making a general water material, and because my water area is small, it ended up being more like a small lake or pond than a giant ocean. There are some specific issues related to making a large ocean material (as you pointed out) that I didn't cover. If I were making a large ocean, I would use a single plane, and I would use Unreal's tessellation feature to increase the triangle count close to the camera and reduce it further away from the camera. Or I would just use the new water system that was added to Unreal in version 4.26.
@@BenCloward appreciate tour response. I do have a tesselation power and tessellation multiply parameter but I’ve found that sometimes it simply doesn’t work. Very bizarre. Anyway thanks for your reply it’s nice to know I’m not going crazy.
Hello there! Thank you a lot for your gamedev community contribution. One question for you, it seems your normals are getting completely flatten during your wave animation for a short period of time. It started to happen right after you added additional gerstner waves. Why it happens? How can you fix this? Thank you good sir!
Your tutorials are excellent and I really appreciate them. I am learning and working to implement all that I can in UE5. But sadly uses such as the waves do not work. I hope one day in the future you can show how to do something similar to this in UE5. Again, sincerest Thanks for all you do and teach!
@@davidburdick7377 Hi, I have also struggled with this, but I found a way around the exclusion of Tesselation in UE 5. First enable the "Modeling Tools Editor Mode" plugin. It`s under edit/plugins from top top left drop down menu in UE 5.1. Then UE will prompt you to restart. Now select Modeling Mode from the drop down menu where you select the mode u want to use, Selection, Foliage, Landscape, ect. Under shapes, create a box and scale and position it where you need your water surface to be. After that, with the object you created selected, scroll down in Modeling mode to MeshOps and select Remesh. Up the target triangle count form 5000 to something much higher, 100000 seemed to work just fine for me. PS: Also, if like me, you are this far along with this water shader creation, you already have a water surface created, so an easy way to replace the old surface(the one with the standard triangle count) with the new surface, is to use the same Location and Scale values, under transform in the details panel in the outliner, that you see when you select the old water plane. Just copy and paste those values into the corresponding fields of the new surface you created then delete the old surface and drag your water material from your content drawer, unto the new surface. You should now be able to continue the tutorial and create waves without any issues! I hope this helps!🙂
Regarding the mathematically-generated waves on the plane - could you not just reuse the surface normal map, perhaps scaled up once again, as a mesh displacement modifier? It seems to me that that would solve your realism problem just as easily without introducing a whole bunch of node math into the shader, though I have not implemented it so I don't really know that. Assuming it worked, what would be the difference in computational expense?
Hey there! I'm creating an ocean shader along with your tutorial and I was wondering is there was a way to make the waves smaller closer to the shore? The depth fade node creates an error when I tie it in so thats a no go.
One way to do this would be to project a static texture top-down in world space. You could paint black to represent the land and white to represent the water. Then multiply this texture by the height of your waves.
Awesome tutorial series thank you ! Do you know if it's possible to get the world Z-height position at a giving location when using Gerstner Waves ? (the surface position in other word) Thanks anyway :)
Hey ben , i am in UE5 and while follwing this tut i came to know that they removed tesselation ! what are my alternatives ? can i use WPO for this animation ?
Hey Ben, is how would one set up a static mesh like a bucket to move a long with the waves? Also would love to see something with flowmaps and water next!
I know that physics and buoyancy (floating bucket) would be really cool to get in to - but my channel is focused specifically on writing shaders - so I don't want to get too far spread out in what I'm presenting. I can put flow mapping on my list of videos to do though - that's a great idea - thank you!
Hi Ben, I couldn't find the Tessellation rollout in the shader to follow the tutorial, I'm using UE5, I think tessellation is no longer possible, is there any way to work around this?
The work-around in UE5 is just to use a plane with more polygons. You could create a higher poly plane in Blender or other 3D software and bring it in to Unreal instead of using the tessellation feature.
Excellent tutorials! They've been the most helpful set I've come across. It's a little hard to tell from your video because you don't zoom out of the water far enough, but is this method supposed to stretch the plane that it's applied to? I've made a similar box test environment, but my water plane stretches in and out of the bounds after adding the gerstner waves.
To all UE5 users, tesellation is no longer a feature. You can still have this effect by adding polys to your waterplane instead of tesallating by distance. Its more expensive and not ideal for games but for a realtime scene it will work fine. For reference i am using a 500 meter by 500 meter plane at 1.2 million polys no problem at all.
That is correct. So you can do everything except the tessellation. If you just start with a plane that has more triangles to begin with, you should be fine.
Hi Ben ,i did exactly the same as you at the video,but untill i deep my camera inside the water the waves dont appear,maybe i did some wrong,wonder for your help!
There could be a lot of things that cause this. Is the tessellation on your mesh high enough? What is your tessellation multiplier set to? Is your water mesh larger or smaller than mine? Did you try adjusting the wavelength constant value and the wave height constant value?
@@BenCloward fixed it,there was an issue related to const values,had to change them a bit.Now I`m facing another problem,my refracted image is moving ,but theres like a permanent shape of my stones blue coloured and they dont move,but the image below water is moving
Tessellation is not a feature in unreal 5. I'm pretty sure they just want people to use nanite for now. It pretty much does the same thing as the tessellation multiplier, but better. But for this case I don't think it supports refractive surfaces sadly. Hope they add support for that soon. You can use the modeling tools to subdivide it yourself. With your model selected press shift 5 to open the modeling tools and then find the subdivision tool. Choose the amount of times you want to subdivide, then press accept.
Great video. This series is awesome. I do have a question though... how come you don’t use parameterised values and a material instance? Would make showing amendments to your input values a lot easier! I noticed this about all your videos. The content is awesome though. Keep it up.
That's a great question, James. Thanks! There are three reasons for this: 1. Full disclosure - I'm still pretty new to Unreal. The main engine I use at work is Frostbite - so there are some things I'm still learning about how this engine works. I know that you can expose parameters, instance the material, and then tweek the params in real-time, but I guess I haven't gotten into the habit of doing that yet. 2. There are really two main stages of shader development - setting up the math, and then dialing in the parameters. In these videos I'm mostly showing the "setting up the math" part, and I'm leaving the "dailing in the parameters" part as an exercise for the viewer. 3. Exposed parameters are more expensive than hard-coded values, the the fewer parameters you can expose, the more efficient your shader will run. So when I'm developing the material, I like to hard-code everything. When I'm ready to put the material into production for the artists to use, I go back and expose only a few specific params that I think they will use. I guess I've never showed that stage of development in my videos. It's like a clean-up and polish pass for me. Having said all of that, it's a good idea to show that process, so I'll look at doing it more in future videos. Thanks!
@@BenCloward I like to make almost everything parameter and once I got the good values it's time to hardcode those that need no artist direction. Btw, thanks for all these videos. I've learnt almost I know about UE4 shading thanks to you and your fine work.
In searching for the answer to my question, my eyes must glaze over. The question is how to turn on tessellation in the material node in ue5. Is it even possible? I am loving your tutorials for both quick get it to work and the greater understanding of the engine it brings. Thank you.
I really want to know that in UE 5，world displacement and tessellation have been abandoned ,now you can only use god damn Nanite to do tessellation ,the key is that nanite is only supported in static mesh and not used for translucent material. So I really want to know how to follow your tutorial in UE5.I have been get stuck by god damn UE 5 for about 2Days!Anyone help me?@Ben Cloward
Hah! Eric A. Anderson (@edoublea1) is an awesome tech artist, very talented shader artist, and a good friend. I've learned a lot from him and really admire his work. I'm sure we borrow each others ideas all the time.
Right - the part where I use tessellation to subdivide the mesh isn't possible because tessellation has been removed. So you just need to use a plane that already has more vertices instead.
So this series has been great and has taught me a lot. But something really strange is going on with the surface of the water. th-cam.com/video/roAM2-f9-dk/w-d-xo.html There's this weird grainyness to the reflection and also some places where it looks less like water and more like the T-1000 from terminator. I've got back through your videos like 3 times and as far as I can tell my nodes are connected to the same ones as yours. Any idea of what I could have done wrong? Again, thanks for this awesome tutorial series.
Can you make sure that your normal map is set to NormalMap (DXT5) for its compression setting, and the sampler type is also set to normal for your normal texture settings?
Great work overall, but you show the steps without explaining how you come up with this graph. How one can learn the thought process of coming up with something like this on its own? That tut would be way more valuable than blind pushing buttons and nodes. Just sayin'...
Hah! That’s a pretty strong opinion you have there. The thing that I like about tessellation is that I get detail close up when I need it and it goes away when the camera is further away.
Probably the easiest thing to do would be to make a plane in Blender or Maya or other 3D software that has more triangles than the default one that's already in UE and import and use that instead.
This is the best tutorial series I've ever seen.Thank you!

Tessellation is not a feature in unreal 5. I'm pretty sure they just want people to use nanite for now. It pretty much does the same thing as the tessellation multiplier, but better. But for this case I don't think it supports refractive surfaces sadly. Hope they add support for that soon.
You can use the modeling tools to subdivide it yourself. With your model selected press shift 5 to open the modeling tools and then find the subdivision tool. Choose the amount of times you want to subdivide, then press accept.
Great video. This series is awesome. I do have a question though... how come you don’t use parameterised values and a material instance? Would make showing amendments to your input values a lot easier! I noticed this about all your videos. The content is awesome though. Keep it up.
That's a great question, James. Thanks! There are three reasons for this:
1. Full disclosure - I'm still pretty new to Unreal. The main engine I use at work is Frostbite - so there are some things I'm still learning about how this engine works. I know that you can expose parameters, instance the material, and then tweek the params in real-time, but I guess I haven't gotten into the habit of doing that yet.
2. There are really two main stages of shader development - setting up the math, and then dialing in the parameters. In these videos I'm mostly showing the "setting up the math" part, and I'm leaving the "dailing in the parameters" part as an exercise for the viewer.
3. Exposed parameters are more expensive than hard-coded values, the the fewer parameters you can expose, the more efficient your shader will run. So when I'm developing the material, I like to hard-code everything. When I'm ready to put the material into production for the artists to use, I go back and expose only a few specific params that I think they will use. I guess I've never showed that stage of development in my videos. It's like a clean-up and polish pass for me.
Having said all of that, it's a good idea to show that process, so I'll look at doing it more in future videos. Thanks!
@@BenCloward I like to make almost everything parameter and once I got the good values it's time to hardcode those that need no artist direction.
Btw, thanks for all these videos. I've learnt almost I know about UE4 shading thanks to you and your fine work.
If you could do a tut on buoyancy as well that would be amazing!
Amazin Series Thank you! How can we apply bouyancy to this?
I’m not sure to be honest. I’m focused on shaders. Buoyancy is a physics thing. I bet there are other videos that show how to do that.
awesome thanks
great tutorial could you do one on how to make a storm like Water.
unprivate video 27 :) amazing tutorial Ben loving my water so far can not wait for foam.
In searching for the answer to my question, my eyes must glaze over. The question is how to turn on tessellation in the material node in ue5. Is it even possible? I am loving your tutorials for both quick get it to work and the greater understanding of the engine it brings. Thank you.
I think that tessellation has not yet been implemented in UE5.
I really want to know that in UE 5，world displacement and tessellation have been abandoned ,now you can only use god damn Nanite to do tessellation ,the key is that nanite is only supported in static mesh and not used for translucent material. So I really want to know how to follow your tutorial in UE5.I have been get stuck by god damn UE 5 for about 2Days!Anyone help me?@Ben Cloward
Instead of using Nanite, you can just use a mesh that has already been tessellated. IE, do the tessellation in Blender or Maya.
@@BenCloward thank you !you save my day!
天，这教程太棒了吧
谢谢!
Parabéns exelente, uma pena o Brasil, não ter um professor. assim como você...
Fico feliz em poder ajudar!
I use UE5 and i dont have Tessellation!?
I swear the artist on Myst VR followed these tutorials lol
Hah! Eric A. Anderson (@edoublea1) is an awesome tech artist, very talented shader artist, and a good friend. I've learned a lot from him and really admire his work. I'm sure we borrow each others ideas all the time.
@@BenCloward Oh wow, small world!! :D
i feel like i want to jump into this water and drink 🤣 looks so juicy
UE5 does not have tesselation in materials anymore
I think they just added it back in using Nanite in the most recent version, but I haven't used it yet.
Hm this methods does not working in unreal 5
Right - the part where I use tessellation to subdivide the mesh isn't possible because tessellation has been removed. So you just need to use a plane that already has more vertices instead.
Teaches how to leave the waves for a sea project, so that the waves go towards land just like in real life
So this series has been great and has taught me a lot. But something really strange is going on with the surface of the water. th-cam.com/video/roAM2-f9-dk/w-d-xo.html There's this weird grainyness to the reflection and also some places where it looks less like water and more like the T-1000 from terminator. I've got back through your videos like 3 times and as far as I can tell my nodes are connected to the same ones as yours. Any idea of what I could have done wrong? Again, thanks for this awesome tutorial series.
How did you solve this problem? I do not know why I can't add a web link, youtube always delete my comment……
Can you make sure that your normal map is set to NormalMap (DXT5) for its compression setting, and the sampler type is also set to normal for your normal texture settings?
I like you
Great work overall, but you show the steps without explaining how you come up with this graph.
How one can learn the thought process of coming up with something like this on its own?
That tut would be way more valuable than blind pushing buttons and nodes. Just sayin'...
no no no noNO TESSELALLTION IS BAD, i bet you don't want to use too much space to just render water, there are a lot of things to do
Hah! That’s a pretty strong opinion you have there. The thing that I like about tessellation is that I get detail close up when I need it and it goes away when the camera is further away.
Hi Ben.I use UE5 and i dont have tesselation mode in the datail .What can i do ?
Probably the easiest thing to do would be to make a plane in Blender or Maya or other 3D software that has more triangles than the default one that's already in UE and import and use that instead.
