Hello there, it's been a while !

I've found a bug :
If i use a bitmap (hdri mostly) in Reflexion override and not in the environment (lights), i get some strange rectangular errors in the render : longer to get less noisy and eventually turns black.
As soon as i put the same hdri in the light environment, instead of black color, it works.

Quick solution is to put the same hdri, but via  one CoronaColorCorrection with expo to -20, so it is black for lights, but normal for reflexions...

I didn't manage to reproduce this. If it's still happening, please provide a screenshot or a simple repro scene.

Hi Maru,

I could not replicate this, maybe it was scene dependant or so.
As i had the known "veeeeery slowww & lags" while IR, i've changed several things, bios, drivers and Corona 12.1 hf 1...

If it comes back, i'll save the scene and some screenshots

Hello Maru,

Ok, forget it : i can't reproduce as since then i've upgraded to corona 13 daily build, then back to corona 12 up1 hf1... Maybe it solved it...

Best regards.
