Hi @Mugen87, took me a bit, but finally I managed to reproduce it in a fiddle.
I put a 2s timeout to switch from the default renderer to the composer.
By default (with the OutputPass added), you can see the scene turning “brighter”.
If you comment it out (line 594
) and rerun it, it will turn darker.
But it will never reproduce the original result.
Forgive the bloated setup in the beginning, I needed to build something similar to what I have.
And really appreciate you looking into it, thank you!
