In Breached we have a lot of digital noise/glitch effects. While we mostly used the wonderful “Sci-Fi and Glitch Post-Process” package, I’ve wanted to add a bit of uniqueness to UI noise effect and assembled a material function for distorting UI texture UVs.
It uses a bunch of procedural noise generators, panners and a texture mask to apply specific distortion pattern.
The function turned out to be quite flexible, so I’ve thought it could be useful to share it. You can grab archive with the function and texture mask here: http://goo.gl/5WBkmC
Just drop the unzipped folder to UE project and the function should become available as “DistortUV” node.
