V-ray BR/BR Bounces

#1

Hey all,

I ran into a problem on this incredibly heavy scene where I run out of memory during GI caching, so I’ve decided to skip it altogether and use brute force + brute force.All is fine, except now I’m wondering about light bounces as by default brute force is at 3 bounce, while light cache is at 100.By switching to brute force for both primary and secondary engines, I get one spinner for bounces.To get the same number of light bounces ,should it be set to 3, 100 or 300?

not more than 10… it would take ages to get an final image with 100…

Would personally not dare go over 3-4, unless you have a good DR setup and rendering over night, or just don’t care about rendering times.

In my experience it doesnt add that much to rendertimes? I rendered with 100 bounces more than once.
I must admit i havent experimented much with its effect on rendertimes though…
