Corona 6 for 3ds max // Interactive lightmix issues

[hrb]

Hi there,

I just upgraded from corona 5 to 6 on 3ds max 2019/2020.
We are used to use the lightmix feature with various hdri at the concept stages, to choose interesting lightin and propose some options to our clients.
Since yesterday, I've struggled with that feature ( that wasn't maling any problem before ) that create an amazing amount of noise, even though we have stats like 0.93% of noise in the image.
I tried using the same hdri alone and we don't have this problem. Same thing with a corona sun.
I've tried varioussecondary GI solutions to see if it could be the cause of the problem ( UHD cache, Path tracer, 4K solver ), but nothing changes.

So, maybe am I missing something, or there's a bug.
I'm going back to corona 5 for now.

What's your opinion about this guys ?

All the best,

Hugues
