Create high-performance 3D GPU particles in Unity 6! In this tutorial, we build a complete GPU-driven particle system where thousands of real 3D meshes are simulated and rendered entirely on the GPU using Compute Shaders. You'll learn how to efficiently simulate particle behavior, update structured buffers, and draw massive amounts of custom meshes with minimal CPU overhead using Unity 6’s new Render Graph system. Perfect for explosions, swarms, crowds, or any effect that needs huge numbers of animated 3D objects running at smooth framerates.
