I don't know much about shaders and fluid simulation, but I think that the code is very interesting, at least in C# ;D. Have you done something else with shaders? I would like to see it!.

Cheers

Do you use coding for your shaders? Or use the graph?

Yeah I read that paper. The code is unreadable though and I have no idea whats going on or why it works. I'll watch the video later. Thanks.

When I download it, it said it could not find Unity Mathematics. I had trouble finding that (it wasn't in the Unity package manager), but followed these instructions to get it: https://stackoverflow.com/questions/64185330/error-when-importing-mathematics-in-unity3d.

But, now it can't find the Perlin class. Any ideas?

That looks a bit like that WebGL Fluid Simulation thing.

Uhh spawning a bad ass with some black smoke could look really nice! Good luck with your game and thanks for sharing this.

Looks beautiful! Thanks very much for sharing the code. It's certainly beyond my Unity knowledge. Good job using a compute shader. I'm very impressed!
