Screen Space Warping of Outline Post Process Material

Development Rendering
1

Hey Guys,
I’ve got a Post Process Material that draws outlines on my objects, and I want to be able to warp it slightly in screen space using a screen aligned texture (just two grey scale images, one for each axis with black warping in negative x and y, and white in the positive). I can’t figure out how to get my textures to affect my outline. Is there such a thing as UV’s for the screen itself? For reference, The effect I’m going for is the outlines from Life is Strange.

you will probably have to do the warping to all the ScreenPosition nodes before they go into the SceneTexture:CustomDepth in the material for “accurate” results. it may be possible to do it later in the graph but i’m not sure right now.

I thought that might be the case. Do you have any examples on how to do that? Everything I’ve tried so far is basically turning my outline into a solid color with an alpha on it.
