To use Depthkit Core in HDRP, you need to use the Depthkit Core + Shader Graph prefab.
Check out our latest documentation for the Core Expansion here, and specifically where we show how to use Shader Graph which is needed for HDRP and URP.
I’ve just followed the instructions and it works wonderfully.
Is it possible to add the Zero Day’s look to a clip that is being played by the Depthkit clip + Core shader Graph and if so where would you add it so that it works together.
