Material Effect Collection

Hey everyone!

I’ve been playing with Unreal model and post-processing shaders and wanted to share the codes with you, in case somebody will find them interesting.

I’ll be really happy to hear your thoughts on this and if you use them feel free to share the projects images/videos. I’m always up to try doing more (mostly NPR shaders), so feel free to drop your suggestions for the effects. Hope this will help someone. Cheers!

@Luffyyy don’t worry about the mosaic, that’s caused by the tiling, my texture is normal 1x1 If you need to “squeeze” the texture try looking here: https://answers.unrealengine.com/que…uv-tiling.html

The solution offers “moving” the texture uvs. If you want to get the same effect as me, use multiplication node instead of add.
I don’t think it’s necessary to change value of grey when it comes to textures, it really depends on what you wanna achieve, the final effect depends on many factors, not just texture, so just use whatever you like and you can tweak if later, if it doesn’t meet your expectations.

Okay, I just tried to set it up :

(see picture)

But it doesn’t work at all ahah… It’s like a basic texture applied on a mesh, and it doesn’t react to anything like it does in your video. What did I do wrong ?

EDIT: Oh okay, I was not setting my material to Masked…
But anyway, other question comes to my mind, is there any way to apply this as a post process material ? In order to apply this to the whole level ?
