Rain Effects On Terrain - Terrain Shaders - Episode 18

A step-by-step walkthrough for adding rain effects to terrain in Unity using Shader Graph. Covers importing the production-ready shaders sample from the Unity Package Manager, adapting the built-in rain floor subgraph to work with a custom 4x4 matrix-based terrain material system, creating a custom puddles terrain subgraph, wiring up is-raining and puddle-size parameters, and using height data to break up puddle edge shapes for more realistic results.
