Hello

If I render with Denoiser ON, the mini preview window shows a wrong exposure.. very over-exposed compared to the actual render image.
When using No denoiser.. mini preview is good and in par with the render image exposure.

Hey - yeah - I've noticed that too.
Looks like double exposer or something.

My setup was IBL + a few light panels - maybe IBL causing such behaviour.

Cheers,
Artem.

as far as I tested.. IBL or not IBL does not make a difference.. even with just a few light panels

Hmm ... I haven't seen such behaviour before .. not that it greatly affects my workflow tbh but still a bit strange.

Maybe it happens if you hav more than one camera in a scene ? I dunno - like double exposure ? it is definitely something to do with a camera settings .. I'm pretty sure.

Any tech dudes can give us a hint ?

GPU Transmissive materials look wrong too, over-contrasty compared to CPU. Compensating for the over brightness still does not look right.
But this is academic as Maxwell FormZ renders my nurbs objects with zero-smoothing on tesselated facets regardless of settings, same as in 5.1.
