Subdivs of refraction (glass material) show no effect

[Micha]

Hello.

this problem is seen at Vray for Rhino and I ask me, is this a known problem at 3dsmax too?

I use a closed glass plate in front of an emitter. If I setup the subdivs like at the screenshot, than I get a noisy refraction only. If I change the subdivs of the refraction layer, than the noise change only a very little. But if I setup the scene ala Vlados universal setup (adaptive amount 1 and noise 0.01 + Adaptive QMC 1-100) I get what I want.

Any idea what is wrong here?

Regards,

This works fine in 3dsmax; I am not sure why it doesn't work in Rhino, but it may be that the subdivs parameter is not correctly transferred to V-Ray by the Rhino plugin.

Best regards,

Thanks Vlado. I will post it at the bug section of VfR.
