Amazing add-on for Blender.
Geometry Node based cloud creator.
There is a free version, but the price for the full version looks like a no-brainer.

Back in the summer of 2023, after my cat died, I spent 2 weeks building a particle physics animation engine in Blender Geometry Nodes, entirely on intuition. I also built a system to record animations as curves so they can be played back dynamically.

I’ve been building a basic raytracer in C++ and CUDA. It uses OpenGL-CUDA interop for real-time visual feedback. No CPU transfers, all on the GPU. Progressive rendering makes a big difference.

Decided to check out how water is rendered in Counter-Strike 2.
Given how interactive water in CS2 is, I expected to see some cellular fluid simulation, but turns out they just use a low-resolution off-screen buffer with flat 2D decals used for various aspects of water. Reminds me of HL2 water :)
