Free Unity 2019.4 Project: 1 Million Grass Instances on Mobile URP (NiloCat)

Overview

Colin Leung (NiloCat) shares an example URP project that demonstrates DrawMeshInstancedIndirect drawing millions of grass instances on mobile devices. It keeps things as simple as possible: a simple CPU cell frustum culling, a minimal compute shader GPU frustum culling and then a single DrawMeshInstancedIndirect call.

The grass shader handles lighting, animation and grass bending, and the README lists test results on midrange Android phones. The project uses Unity 2019.4.15f1 and is free under the MIT license.
