Free Unity 2021.3 Project: CS2 Volumetric Smoke Grenades Recreation (Acerola)

Overview

Acerola (Garrett Gunnell) shares the code associated with his video on recreating Counter-Strike 2's responsive smoke grenades in Unity. The smoke spreads through voxel based propagation with a limited flood fill, alongside a mesh voxelizer.

A generalized volume ray marcher renders the smoke, with a tiled Worley noise generator for detail and an SDF based smoke deformation that is marked as not performant. The README states it is not a production ready asset, the project file is Unity 2021.3.15f1, and no license file is included.
