Short description of error
transluscent bsdf appears in environment pass

Exact steps for others to reproduce the error
open file, go to compositor workspace, press f12 click on the viewer node. Notice the environment pass includes the monkey. This makes it more complicated to perform colour correction on just the environment. only appears to happen if transparent glass is enabled in the film settings of the render properties.

@michael campbell (3di) The monkey is gone from the environment pass in Blender 3.0, but the remaining scene looks a bit different to me (Compared 2.83 and 3.0).

2.83:


3.0:

I guess the original issue has been fixed though?

@Thomas Dinges (dingto) seems the fix has generated the bug you mentioned above. What was happening in 2.83 was correct (minus the monkey). I've also noticed that custom AOV's have also stopped working, they now render completely black:

Closing then, as the original issue has been fixed. I see you reported the new issue in T93278, thanks for that!
