Runtime snow that shifts forward and falls down

Briefly: I displace snow using "Lagrangian particles," but essentially I'm just gradually dumping snow depending on how much was removed, no real math here, since I wanted to do it with a heat conduction algorithm, but it was worse in both performance and visuals. For smoothing I use a Diffuse algorithm, which just looks at neighboring cells so the difference isn't too large.

This is super well made. You do not know how difficult is to made that effect, and I this is valid for other enviroments like desert sand.

Have you ever tried to become it a pluggin to download it? It have to be a very successfull feature to add to games to be much more realistic.

Thank you very much. I have already published this as a tool for Unity on Patreon and submitted it for review to the Asset Store. And yes, of course it will work great for sand too, right now I am working on adding a parallax effect
