Animation with brute force flicker free

[thanulee]

Hello, due to vray 3.0 i tried to use brute force for a work that im doing. At the first tests, bf+lightcache as secondary bounces, produced great flickering, while my samples where really high. The same scene with the original im+lc prepass method, worked much much better.

So whats the trick with brute force? Should i have it on both primary and secondary? should i disable secondary maybe the lc produced the flickering? The flickering depends on how much samples i got on bf alone? I cant find nothing on the web to help me in terms of animation with brute force.

thanks
