Vrayhairmtl3 and transmission

V-Ray V-Ray for Maya General
1

So I’m trying to comp some hair that was rendered using the vrayhairmtrl3.
To comp it, I take the spec pass, add the reflect, refract, lighting, and GI passes over it and that will look identical to the beauty pass. However when I turn the transmission above 0 the comp looks different than the beauty. The highlights are not as crisp and the overall color is a bit darker. Is there a way to build a comp to be identical to the to beauty if you want the transmission to be something other than 0?

Please advise.

Thanks in advance!

Hello,

Thanks for sharing. We’ve reproduced this in our environment and will be looking into it to find what’s causing this. I’ll update the thread when we have more info.

This is now fixed for the nightly builds from 21 Dec and later.
