NodeMaterial + Shadows + ShadowDepthWrapper: how does it supposed to work?

Questions

Hi!

I’m building a game and need a custom shaders for weather effects (like snow, rain, etc). I am trying to do this with the help of NME. So the problem I’m facing with is: I can not get shadows (self-shadows and casted shadows) to work with this material. It has alpha channel and I absolutely need it to cast correct shadows not just rects.

I dug through documentation and through examples, looked the youtube channel videos on NME, tried to sue wrapper - no luck. And nowhere could I find this valuable info. Maybe I just don’t know how to look for that info in the end.

I see there is a ‘shadows’ output on Lights block, but I have no clue how do I use it.

Please, explain =))
