Stunning 2 Million Object Gravity Simulation Powered By Compute Shaders

As Technical Artist Safar Isaev, also known as Sofar, explained, he developed this project purely for fun and as a learning exercise in Unity's indirect instancing, saying that it was easier for him to write the system from scratch than to dive into the complexities of VFX Graph.

This screensaver-like 3D simulation is highly performant: Safar optimized the 2 million body problem to run at over 60 FPS in the editor, even while recording simultaneously using a GTX 1650. The developer plans to post more updates on the project soon and hopes to include an Asset Store link as well.
