I’m trying to make a post processing shader/material for an infinite runner like Subway Surfers. In SS they spawn their map pieces all in a straight row then use the shader to simulate the turning. I’ve got a cubic lens distortion shader working from a tutorial from http://eat3d.com/free/ue4-shader-fx-cubic-lens-distortion but I can’t figure out how to get it to work without a texture. The post processing effect simply shows the texture and not the rest of the game.
Can anyone point me in the right direction as to how to do this? I haven’t used UE4 long, I’ve got more of a Unity background. Would it be possible to find and grab the material/shaders from the VR demo and use that?
