(DivX 5.2)

Maybe I've to tweack some other value...
Tell me

[plastic_]

try increasing the global subdivs multiplier in the monte carlo rollout.

[Fabrice]

Where is this parameter.
I don't know it...

QMC?

i think he means the QMC. not sure...

Manual:
QMC (Quasi Monte Carlo) sampling is employed throughout VRay for every "blurry" value - antialiasing, depth of field, indirect illumination, area lights, gossy reflection/refraction, translucency, motion blur etc. QMC sampling is used to determine what samples should be taken and, ultimately, which rays to trace.

Instead of having separate methods for sampling each of those blurry values, VRay has a single unified framework that determines how many and what exactly samples to be taken for a particular value, depending on the context in which that value is required. This framework is called the QMC sampler.

You should increase the hemispheric subdivisions of the irradiance map and/or reduce the noise threshold in the QMC Sampler rollout.

Best regards,
Vlado

I tried tweaking the QMC parameters without noticeable results.
But with 100 hemisph subdiv instead of 50 I get quite good results.(...with much more render time of course)

Thanks for the tip Vlado !
