There was a problem hiding this comment.
I would also recommend using a roughness value > 0 (or several values, or adjustable values). The example only worked before for mirrored reflections; now that it uses actual PMREM, it will also work for other roughness values, so we should demonstrate that to help ensure it does not regress.

Related issue: #23152
Description
#23152 revealed a small issue in
PMREMGenerator. When working with cube render targets, the same flip logic for px/nx is required like in the material shaders.
