Adding Shadow Casting to Grass Baked with Compute Shaders ✔️ 2020.3 | Unity URP Game Dev Tutorial
✔️ Works in 2020.2 ➕ 2020.3
Grass is one of those things that's deceptively difficult to implement. I've taken a stab at it in this series of videos, showing how to generate grass blades using a compute shader, and animate it using the vertex function of a graphics shader. In this video, I modify previous scripts to add shadow casting to the grass blades, as well as show a trick to lighten shadows without global illumination.
