Hello. I’ve been testing corona with this scene. In this bathroom, everything seems ok in 10 mins, but the black part. The black material doesnt seem to get rid of noise or it takes too long. Is there a problem or is this how it works? By the way, i’ve tried the material color as 0-0-0 (black), or a little lighter (2-2-2). Doesn’t seem to solve the problem.
here’s the scene if you wanna check it out yourself. (3ds max 2014)

i looked at some other posts, it’s because of reflection isn’t it?
upload your scene in max 2013 or 12 version please
but i’m using 14. is there anyway to convert it to older versions?
file > save as > roll down “save as type” and chose 2013

Maru was fastest 
Why you use CoronaLight in the windows?
Here you go. 3ds max 2012.
I didn’t really like the environment light. Shadows and colors are better with corona light i think.

Is it made with A4? I don’t know if it’s because of 2014>2012 conversion but some really strange things happen when I open this scene.
What is A4?
BTW :on second thought, just corona sky is pretty good, too. But my main problem is the black material.
A4 is Corona Alpha V4. Your scene is made with this version, right?
+1 for me too! Even after reset renderer.
Yes it is alpha v4. try this scene. it should be fine. max 2013

When I render this scene it takes AGES to compute initial pass and when I press cancel it freezes and blinks a few times until “passes 12/12” are complete. Looks like it’s corrupt? I’ll try merging.
The same is here. I can’t stop render in a while
And why you switch Gamma off?
same thing happens to me, too. What’s the reason?
Gamma was 2.2, it makes black become kinda grey. 1.0 is fine, than i can change it in photoshop if i want to.
Deleting the active camera and creating it again fixes the 12 passes issue. That’s a progress.
probably some multipass effect on the camera?
