Problem with 3DSMAX et CORONA RENDER

[romullus]

The stats looks good, i don't see any issues there and also 2 completed passes in 3-4 minutes seems pretty reasonable speed for 4K resolution.

can you estimate the time you would take to get between 3 and 2% of noise level?

I can't, but Corona certainly can and will do that for you - just wait till 5 full passes will be completed and you will get quite accurate estimate of remaining rendering time.
