More matte Paint like these would be great!
I want 3d photos motion make ,3d photomotion pro software type 😌😌
Thanks for all your videos, man! Always happy to see you post!
Thanks Marko! Glad to have you here!
I find it fun watching the younger gen recycle techniques which have been around for years! (in a good way) I Used to do this in after effects 15 years back, and I still use that method today.
Hi Claimer, Awesome! Yes it's crazy how long this method has been around. If it's not broken no need to fix it right.
Ha, was just thinking the same thing! I'm now learning how to do in Blender what I knew how to do in After Effects 20 years ago (albeit much more crudely).
I'm with you on this. I remember doing this with Electric Image Animation System (software that cost about $10k running on a Mac IIfx, which also cost around $10k) which pioneered "camera projection" in 3D software as we know it today. EIAS was used in feature films for the longest time (it was used by John Knoll and his team at Industrial Light and Magic in the Mac Rebel Unit and was use extensively for the projection mapping (camera mapping) capabilities. The renders coming of EIAS were outstanding and looked filmic straight out of the box, nobody could touch the real "motion blur" it produced (not this stair-stepping effect you see with most software today), and it was the fastest software-based renderer (phong) in the world (and likely still is). Oh... also, there didn't seem to be an end to the amount of geometry you could toss at it -- it wouldn't even bat an eye if your scene had a couple million polygons. A true workhorse. But although it's still around (it's gone through several company buyouts/new owners) and it's still amazing --- the development of it is now down to two developers, so updates can so long that they're outdated by the time they're eventually released. Kind of sad. BUT... we now have Blender, which, in my opinion, offers a lot more and can "do it all", and is most current with the demands of today -- and Blender, also, does great projection mapping. :) Oh... the walk down memory lane with EIAS.
Sooooo good!
Thank you!!!
@@LightArchitect Thank you!
Used this method in Game Dev for Decades. It works great if done properly!
Awesome! What programs do you use for Game dev?
@@LightArchitect ignored☹
Wow. Very, very useful. Many thanks!
Thanks Ed! Glad it was helpful!
Another great video! Thanks for sharing!
Thanks!
This is a pretty cool Visual Effects Technique for Blender! Awesome!
Thanks!
@@LightArchitect Of course!
@@jbhvlogs3609 Yup!
This is a great video with detailed explanations. Thank you
You are welcome. Thanks for watching!
Infinite Thanks!! You are Awesome 🙏🏾
Thank you for the support!
@@LightArchitect Very welcome, my Friend!
Brad, again I'm amazed.
Thank you Navid! Appreciate the support!
This is a really effective technique for visual effects!!!! WOW! Amazed as always!
Thank you so much Celebrity subscriber! Glad we are helping you in your visual effects learning journey!
Wow famous person commenting here!
@@JBHMEDIA Yes.
@@JBHMEDIA Lol
Thank you for this! I got a tip for you in return, I believe alt + r resets all rotations on an object, so for example when you add in a new camera or drag an object into the wrong place just hit that and you save some effort :)
You're welcome! And good idea! Thanks for the shortcut! Definitely saves some time!
@@LightArchitect If you already use alt + r, then you'll probably also want to use alt + g and alt + s, which makes the set complete. Deductive logic should tell you exactly what these are for.
Freaking helpful!
a good way to use photos for photorealism more i advance in blender more i realiser how much photos help clearly
Yes they can be really useful. At a bare minimum they help you see what a real shot will look like so you can match your CG elements to the scene better.
great tutorial, thank you!
You are welcome! Thanks for watching!
Awesome thank you for special insight.❤🎉

Hey Bro You are Real VFX Artist
Thank You❤
Hi Ankit! Thank you for the kind words and support! Much Appreciated!
very useful technique. I already knew this one but actually have never applied it yet. Thanks for sharing this quick tutorial. I personally would thank any other tutorial focused on "low spec PC's" since not everyone who is into VFX owns and RTX 4090 lol. So just like this technique I know there must be more smart and simple techniques to achieve cool results without making your PC explode lololo. Thanks man.
Hi Walter. You're welcome. Yes this one is a fairly common technique but I use variations on it all the time so I thought it was time for a simple tutorial. And that's a good idea. Could be fun to do a series on getting the best bang for your buck with less computing power. I too am not working on the most powerful machine.
Learning topology and texture baking will help you make your assets and scenes energy-efficient.
I *wish* that an RTX 4090 was enough to save you in large renders. Gotta choose between a render farm or a car!
Thanks😀 Now i can render cool images!
Awesome Banany!
Thankyou so much Sensei!!
Haha thank you for watching Box Meta. Appreciate you taking the time to comment!
Thank you, very cool

Nice job!
Thank you so much!
Really superb bro. Thank u
You are welcome! Thanks for commenting!
awsome tutorial. A tracking tutorial for Blender 3 would be cool. I already learned that but any more pointers on that would be really cool. thank you
Hi Surrealist! Good idea. I'm not sure how much the tracking process has changed for Blender 3.0 but I'll do some research.
great tutorial buddy
Thank you Tanuj!
Really very good tutorial
Thank you Rajat! Appreciate your comment!
Thanks for sharing 👍
My Pleasure! Thanks for watching again Steven!
thank you 😮
Thanks for watching Hadher!
pretty nice ！
Thank you DL! Appreciate the input!
@5.05 when you add a new material and set to an Emission shader (to get a fullbright result), you can alternatively just bypass the shader and go straight from the Image Texture node to the Surface input of the Material in the shader editor.
Great idea!
thanks for that.
You are welcome Agyab! Thanks for watching!
Hey mate, this is a great tutorial!
Question: Then, when you place an object. Any idea of how to cast a shadow on the floor and walls? without affecting its colors? for that reason, I couldn't just use the texture in the Base Color from a Principled BSDF
YES
Thanks for watching Surreal Comix!
that is a very interesting video.
Thanks Joshua!
convinced, subscriber
Thanks for the support Stephane!
cool
Thanks Micheal!
thank you! is there a way to export the projected texture in a file? i need a projected image to make “3d graffiti “ printing
Super ❤️❤️
Thanks Gowri!
So far so good. Followed everything to a T and it works. My only problem now is that when I add a light to my seen it doesn't light up any of the geometry that I have projected my image onto... Absolutely ZERO interaction between light and projection... Any suggestions?
فديو مفيد جدا ، شكرا 🤍
Thank you so much!!!!!
Super
Thanks Abubakir!
Great video, but I think FSpy is a plugin that makes this whole process a lot quicker and I like to duplicate the mesh, redo the UV for the duplicate, then bake the texture from the projection to the duplicate so I can use the clone stamp tool and paint in the distorted edges where the camera didn't cover so I can pan around. If the UVs are hand done, then you can even get away with using DALLE or stable diffusion to fill in those gaps.
I would only find FSpy useful when there are X and Y lines to match, unless there is a technique to work with irregular backgrounds
You could use fspy to get an accurate camera perspective from an image
Fspy is amazing as well! Good idea!
Would be difficult in this example though as there are not definite Straight edges to use as reference points
Quotes About Hard Work
"Hard work beats talent when talent doesn't work hard." ...
Good one!
After projecting the image onto the desired asset. Can the image/texture on the target mesh be baked out into a texture map based on it's own uv's?
I haven't tried this but I'm fairly sure this is doable.
Hey! How would you go about having shadows interact with the projected matte painting?
Having the same problem and can't figure it out.
How do you make the sun not affect the lighting of the planes ?
Nic work bro..... is this kind of stuff can be used in creating exterior of the train and thn animating it in X drection to give impression of a landscape from within the train?
Thanks Syed! Definitely you could use this technique in the train situation you're describing.
I Love you
:)
Can you export it like that as well? Does it makes the UVs when you project from view?
You can bake the UV's onto their own map. I don't think it creates a UV map that you can use externally automatically though.
hey is it possible to use our own character meshes in horde?
if you have more example or camera projection trickd , i'm for it !,like with a more complex terrain maybe
Hey Paul. Sure I can make a tutorial with more overlapping layers of elements maybe. Appreciate the input!
@@LightArchitect yeah becaue here the landscape is relatively flat ,so it's easier to model ..but i was wondering if that thechnique is possible with a more irregular bumpy , landscape for example , like if the foreground is a bit harder to put together..no worries if you don't do it :)
u should give image link in description to practices
Good Idea. I got my image off of Unsplash here: unsplash.com/photos/73F4pKoUkM0
@@LightArchitect thank you so much ...can you make a video on how to design a set for a 1 mint dialogue scene and shots like two shot and two close-ups of each actor and return back to two-shot (scene shot in green screen )
hey! did you update the Horde Plugin for Blender 3.4 or 3.5?
Hi there! Yes we have tested HORDE up to Blender 3.4 currently.
Please make more tutorials liké this, or maybe recreate one shot from movie to learn us how there are done ? Good Idea ?
Great idea! Thanks for the suggestion!
can u cover multiple camera projection in one scene please ? i mean how can we use it and for which subjects.
HI there. I probably can in a future video yes. Can you elaborate further?
If you're having issues with the *size and aspect ratio of the reference image,* or if you feel like your projection is always somewhat distorted, look at this tutorial. The explanations are terrible but it gives solutions : /watch?v=MDX9B7A3jA4
Did I miss a step in applying a texture to the plane. I saw you unwrap / project from view and then viola!
Hi Dan,
I think so. When we added a new material to the plane we selected the camera background image as the texture.
What if you neeed diffrent angles and not one shot but more shot?
Hi Furkan,
Well you could try and repurpose the projections you've already created for other angles as well. When they don't work though just repeat with a different background and re-project. Hope that helps.
you skipped one of the most important things, and that is matching the camera settings at the very start of the project in blender to the camera that the image was taken on.
Good idea!
After going through the tutorial my projection is all distorted and the sky is where the mountains should be and the mountains are on the ground and the image is stretched in some places. Is this an issue with how I set up the plane? Or did I do something else wrong?
This is most likely because you need more subdivisions on your geometry for the projection to be more accurate. Assuming you did everything else correctly.
@@LightArchitect thanks for the quick reply, I’ll try adding more subdivisions
@@edavidrowley Of course! Glad to help out. Let us know if you have any more questions.
Are you using a trackpad or something? Nice tutorial
Haha just using my touchpad on my laptop lol. Thanks!
So thats how they made superliminal
please help, after I place the image inside the plane, it didn't allign with the image projected in camera as background.
Hi Elordy,
Happy to help but there could be a variety of issues that are causing this. Perhaps you need more subdivisions on the plane before projecting, or maybe the aspect ratio of your image is different than your camera ratio. Hope this helps.
@@LightArchitect I've already figured it out, I just didn't selected the plane when I was adding image to be projected. Thanks for the response though, really appreciate it.
really cool video, but it would be really helpful to see what keys you're pressing as you go through it. awesome work nonetheless!
Thanks J1mmyCrazy. Appreciate the input.
I always wanted to know how this was done
Awesome! Glad to be able to inform you Bakhtrian. Let us know what you would like to see next!
How would one fix the parallax?
Hi Steel Studios,
I I think rather than fixing it you have to work around it. The parallax is a side effect of this technique. If you want more accurate 3d models you have to create full PBR models and materials instead which can take a bit more time and computing power to render.
What happened to the building addons? is it paused?
Hi Martin,
Not paused just a bit delayed. We are about to release a new space mini kit for CityBuilder3d.
if you click the camera and press alt+R you don't need to manually delete the rotation
Awesome! Thanks for the shortcut Conor!
@@LightArchitect no worries, alt+R, G, S etc resets those transforms. Very handy
@@conorsvfx Love it. Gotta add those shortcuts to my mental toolkit.
clear video, however, in the end, you added the grass, the tree, but you didn't show us the result with the movement of the camera .... if the camera stays still, we might as well compose the scene and put a plan like background...
Hey Marco. Fair point. Yes if the camera doesn't move the projection makes no sense. Probably should have shown a little cam move there after building up the environment in the foreground more.
MAYBE SHOW HOW TO EXPORT THE PROJECTION AS A TEXTURE??????
Good idea. Thanks for the input. :)
Which video was it that you made that shows the camera projection you're showing in the first 20 seconds of this video? I've seen a similar projection on Top Channel with a city destruction tutorial, but I couldn't find the video you said you recently made with a scene like that.
Hi Stephen. I think you are referring to this one here: th-cam.com/video/a-ihpo5FoUg/w-d-xo.html
@@LightArchitect Ahh, there it is, thank you!
Your pc configuration....?
Very basic 2017 Macbook pro with a 2.9 GHz Intel Core i7, 16GB Ram, and Radeon Pro 560 4GB graphics card. Would recommend way more than this for anything with simulations and such. Might upgrade myself very soon. Thanks for commenting!
because? shows the result of other videos, but not the video you were making
Bro my PC can't run this version of blender because it just don't work but I can't find any people with a good knowledge to teach how to do VFX with 2.7 or less. And I know this is possible because 2.8 has born after the VFX
Put your keyboard on a hand towel or something. Nothing worse than the constant noise of the keyboard
Haha you are right. I should just get an external keyboard soon. Thanks for the input!
uv mapping doesnt pop up when i press U
Make sure you're in edit mode
Yes make sure you are in Edit mode. :)
Sir Can I run Blender on an Intel Core i3 7th Gen (4gb Ram, 480gb SSD)
Of course not! You need a mainframe supercomputer!
@@flonkplonk1649 should have told earlier I have been using blender on i3 7th gen ( 8gb ram, 512gb SSD )
Now I have to uninstall it and buy a mainframe supercomputer from my local grocery store
Yes but rendering times and general performance speeds won't be *amazing*
Cnat help but notice hes on macbook :)
:D :D
How make this model in blender???
th-cam.com/video/DPC9K5ZCoL8/w-d-xo.html
it does not make sense that they do not show the render of what you were
Hmmm interesting. We'll try and show some more examples next time in addition to the one we showed. Hope this video helped you understand the concept of camera projection better though.
...I wish it didn't feel sometimes like you can't wait to get done with the video while you are presenting it.
I personally find it to be a mistake to have the music last too long either at the beginning or end.
It adds an anxiety vs pleasantly guiding one through the experience. Anyway it might be just me but there is a sense of imapatience in your tone by the end that indicates you can't wait to be done and with the music coming up that sense is magnified like: Here comes the end! I'll be done any second now....
In the case of this video I didn't quite get any sense of just exactly why I would use this techniques. Forget trying to get through it quick to avoid the pain of presenting it. Demonstrate the positive benefits of the moves you make not repeatedly mention that it can be better but you aren't doing it that way cuz "for the sake of THIS tutorial [which it seems you can't wait to be done making] it doesn't matter if you do [X] really well or not.
You say there are limitations so, OK, demonstrate the utility vs announcing the shortcomings so the limitations are clearer. Otherwise I don't even get why you are making the video.
Hi Craig,
I understand what you mean. Sometimes I try and cut down the ending portion of the video if it's not really a part of the tutorial itself so the video doesn't seem too long. In this case the addition of the grass and tree at the end was making the video go longer than 13 minutes if I explained everything rather than giving an overview. Your comment is noted for the future though thanks!
Oh and to answer your question regarding limitations of this technique. Most of the limitations occur when the camera moves too much and the parallax of the warped projection on the 3d geometry is seen.
don't see why you wouldn't just use unreal engine & megascans
Hi MtGox. You could. Megascans are still PBR assets though so would require more memory for deep backgrounds than this. I guess with Unreal engines new rendering system it could be as good though. I haven't tried personally.
very noisy keyboard ;)
Haha yeah I'm a bit heavy handed. I'll try and dial it back.
very aggressive presentation of the material, it's unpleasant to listen to
Appreciate the input Super Six Four.
Its totally waste of time watching this video, its nothing more in specific to understand about the camera projection
I'm not sure I understand what you mean. But sorry it wasn't useful for you. This video could help you understand camera projection better as well --> th-cam.com/video/a-ihpo5FoUg/w-d-xo.html
