SRP DrawingSettings.overrideMaterial no way to retrieve the original material's properties

I'm writing depth and normals with an overrideMaterial, this used to be done with Camera.SetReplacementShader. But since now the material is overridden, not just the shader, the properties from the original material are not retained. In this case they would be needed for alpha clipping. Is there a way this could be done? Also appreciated if someone has an idea on how to get alpha clipping working in an overrideMaterial. I could add a shader pass to all shaders in the scene but I don't want to.

 

hi i found resolution to handle the problem. use SetPropertyBlock to ref your property name then you can retrieve it.finally, dont forget to clear the blocking
