Unity Volumetric and Physics Fog Demo
Nearing release for the Game Developers Conference 2021 (July 20) as an open source project.
My presentation together with Eli Landa in the Technical Artist Summit will explain a bit of the math and computer science involved.
The particle system we have developed uses many aspects of Unity to allow a volumetric shader fog effect to have particles anywhere in the game world and interact with any colliders.
We have added a few more basic controls for configuration to help with adjusting for fps depending on what kind of effect you would like.
Unfortunately, video encodings do not play nicely with the visual effects we are designing.
