This is an sea&cloud&sky integrated project for height based & atomspheric fog rendering for URP (Unity 2022.3+ and Custom URP 14.7).

Atomspheric Fog (Height based)

Height based & Sky Fog

Forward+ Lighting

Now supports Unity 2022.3

1.To use AtmosFogNode shadersubgraph in the object's shadergraph as follow:

2.To use MixAtmosFog(inout half3 color, float3 worldPos) to object's shader instead of URP's fog builtin-shader code.

For example, in the file TerrainLitPasses.hlsl, to change code as following:

color.rgb = MixFog(color.rgb, fogCoord); -> MixAtmosFog(color.rgb, worldPos); // need worldPos

Currently, there is an unlit shadergraph in this repository that uses the AtmosFogNode (as shown in the above figure) as the material for the cube.
