Question Wrong or buggy SRP batch break description?

Hey there,

I have problems with the batch description of the frame debugger.
It says that the batch is broken because of different shader keywords, but the keywords are identically. Furthermore it breaks the batch because of "the material requires a device state change" which refers to the checkbox for GPU instancing (which is on).

Am I understand this wrong, or does someone has similar issues with the SRP batcher?

All best

 

I guess it could be related to hardware instancing. If you draw one instance of one object and two instances of another, that theoretically would be SRP batcher compatible, one will be drawn with instancing disabled and the other two with instancing enabled. As this is a keyword change, that is not visible in the frame debugger, the error message would be correct.
The enable instancing checkbox of the material does not enforce single instances to get a instanced draw call.

 

I'm not sure if I understood your explanation. So it breaks the batch because of different LODs because it is a different submesh?

 

Could you explain what else could be a not visible different shader keyword?
I don't know why it would break the batch. There are just meshes with exact same material next to each other :/

 

Could you add screenshots of your framedebugger?
