I created a procedural moisture / rain material with Substance Designer a while ago. I recently created an animated material in Unreal by using two exported tileable 1K texture of this substance. By using material functions, I ended up with tweakable rain material which can be used on opaque and tranclucent materials.
I exported 2 sets of 1k normal maps and roughness maps, which are first for drops, second for flow.
Within Unreal engine, I variated UV tiles, blended different panner results and created a quick scene to see the results.
Hope you like it.
