There was a problem hiding this comment.
The PR renames the type property to the more generic isShadowPassMaterial since isShadowNodeMaterial is reserved by ShadowNodeMaterial.

Description
When
WebGPURendereris inside a shadow pass, the dynamic cache key computation inRenderObjectcan be drastically simplified. The "expensive" partNodes.getCacheKey()can be completely skipped since this key represents the environment of the scene (lighting, environment map, fog and background) which is irrelevant when rendering shadow maps.
