We are using a SimpleLit material for all of our objects. We avoided Lit material, because we don’t need it and we feared it could be slower.
Recently there was a need for a variant of the SimpleLit material that had plane clipping support. Plane clipping can be implemented with ShaderGraph (using transparency masks), but unfortunately ShaderGraph does not support a SimpleLit target.
Fortunately the member Zallist implemented the missing feature as a Unity extension: GitHub - Zallist/unity.zallist.universal-simple-lit-shadergraph-target: This plugin simply adds a Simple Lit material (SubTarget) to the Universal target for Shader Graph for URP . Many thanks to him!
Unfortunately, he can’t maintain that feature indefinitely. But quoting from him, the extension is ready to be merged to Unity. See Get Unity to adopt this officially into URP ShaderGraph · Issue #4 · Zallist/unity.zallist.universal-simple-lit-shadergraph-target · GitHub
Could you please consider merging this code, or alternatively implement the SimpleLit target?
