Technical details
Uses Unity’s API for instancing and custom set up for accessing instancing data in Shader Graph shaders.
All sub-shaders are implemented as subgraphs for the Unity URP Shadergraph.
– Pixelated outlines and inlines based on normal and depth textures. Includes a render feature that enables these.
– Clouds are implemented using 3D Simplex noise
