Let me know Still waiting the new skin shader haha^^

Any news about that Vlado ? And how's that new skin shader going on haha

[vlado]

It looks interesting indeed; for hair in particular it will not really change the way the V-Ray hair shader looks (it is the same BRDF after all) and I'm not sure about the noise either, since V-Ray uses quite accurate importance sampling. But it would be interesting to try and see what happens nevertheless. The microfacet sampling looks way more interesting and definitely deserves some attention.

Best regards,
Vlado
