I haven't tested this to see if it has any practical performance benefit on a laptop. But we should ideally test to see the performance difference before merging. |

A note that this now always runs a render pass. This should either check to see if there are any phase items in any of the phases and if not then early return, or this could be part of #4745 |
…to one They use the same configuration so merging them gives better performance, particularly on mobile, as the attachments have to be written out and read in between passes.

I'm going to close this because a couple of use cases have come up where one may want to run something between the passes. As such, I think the right route forward is to split the opaque, alpha mask, and transparent passes to be run in different render graph nodes so that people have the flexibility to do stuff between if needed. |
