Free Unity 2018.3 Shader: Geometry Shader Grass with Tessellation (Roystan)

Overview

Roystan (IronWarrior) shares the Unity 2018.3 project source for the completed Grass Shader tutorial from roystan.net. The shader uses a geometry shader to generate blades of grass and controls the density of the blades by tessellating the input mesh.

The grass can cast and receive shadows, and a separate tessellation example shader is included alongside the main scene. It is released under the Unlicense, with the fence wood texture sourced from CC0 Textures, and is a free GitHub download.
