Limitations

Some limitations that come with the shader.

2D Renderer

This shader will not work with the 2D renderer in URP.

Direct3D12

Unity themselves mark Direct3D12 as experimental so it's always possible that you see artifacts or drops in frame rate.

SSAO bug

There is a bug in URP where the caustics might not show up on terrain if you have an SSAO pass present which has its source set to Depth Normals.
