Vray hair noise free help

HapZungLam2

I've tried increase/decrease sub div values but still getting noisy render.  Can anyone point me some light?

What if you increase the maximum render time? I don't use Vray so I can't give any more specific tips

Later today I tried to reduce that to 0.0 so it should be infinite.  Increase the max subdiv value to 512.  It gets a little better but the rawLight frame buffer (the one its shown in the middle) is still noisy.  I dont know which attribute that controls that.

Have you tried reducing the colour threshold right down .015 or so?

Try changing the method of global illumination to irradiance map for the first pass and light cache to the second bounce. Your currently using brute force, it's slow and noisy, Irradance map has interpretation settings that smudge the lighting a bit removing noise

Thanks all of you.  Ya I think brute force did more noisy.  irradiance map getting noises to blend better.   I'll try that a bit more.

Any other tip?

hair just needs time to render... i assume under 20min rendertime there is no way to get a clean hair...

Hm. I realize that too.  Your answer confirmed my suspicious.  I'm gonna expect a longer render then.  Thanks for the help guys
