Water on camera lense effect

Hi folks! I’m working on the similar effect (planning to release on the Marketplace once it’s done). If you’re interested visit my thread ScreenFX:Water [WIP] - Work in Progress - Unreal Engine Forums

It does cause some hideous artefacts, is very true. I had wanted to explore a different solution for generating the normals, but didn’t have much luck with the heightToNormals node. Given some more time (and the fact I need to get it working for Cassini), I’ll probably figure it out. I’ll update thread if/when that happens.

As pointed out in another thread you can use ‘NormalFromFunction’ but comes at a large performance impact.

Creating a normal map from a noise map

Your best bet is to look into Random.usf to add your own customized noise function, ideally claculating the derivatives with the noise in one go. Also the default noise funtions are all 3D whilst for a post-process you’ll only need it to be 2D.
