Aug 28, 2025, 6:52 PMDoes anyone here have experience writing shaders for #unity that work with both URP, HDRP and builtin-render pipeline?
The "new" RPs use different includes and have different alternatives to ObjSpaceViewDir, etc.
So far I have concluded that the best solution is to:
- Create one volrend.hlsl with the main shader code, where it conditionally uses builtin shader functionality or URP/HDRP versions based on a "#if USE_BUILTIN_RP" definition
- Create 3 separate shaders, one for each RP, that include the volrend.hlsl (the builtin one first defines "USE_BUILTIN_RP".
- When creating the materials, choose the appropriate shader.
This is madness, but are there really no better alternatives?
