I love working with Corona. One week ago I had to revert back to Mental Ray for one loooooong animation and an old problem came along.
As my computer renders a mental ray-image, everything is so slow. Cant do much anything with my computer when CPU-meter is at ~100%.
How come I can do much everything when I render with Corona and the CPU-meter is at ~100%?
Dont get me wrong, this is a good thing. Keymaster seems to be one hell of a coder :)

Is there same things with Vray? ..I have never used that.
No going back to mental ray - that would be just mental.

Yeah, it is the same thing with V-Ray, I used to play some games while rendering or doing some designs, normally without hiccups. I guess that Corona and V-Ray just manage their resources better. Of course it won't render as fast as when you would let it use 100% of CPU power, but as long as you can live with some lost time it is no problem :)

Nowadays, I am just using another node for rendering so my main rig is free :)

Vray and Corona automatically set process priority when rendering to low, while MR does not. If you want to use your PC while rendering with MR, set 3dsmax.exe process priority to low in task manager.

I find that as well as doing this, changing the processor affinity to leave a couple of free cores really helps too.

Ondra:
There are people with exactly opposite experience. In theory there should not be any problems, but it seems there are some fuckups in windows and/or 3dsmax.
