Thanks Fenric for your reply. 2 questions.

1. When you say:

Quote - It should be possible to take the SDK sample renderer...

which SDK are you talking about? Carrara's SDK or Embree?

2. Do you have a rough estimate of the time it would take for a knowledgeable Daz developer familiar with the internals of Carrara's renderer to implement Embree inside Carrara (not a plugin), including hair and volumetrics?

What I mean is the rough time estimate for a carefully tested production-quality implementation of Embree, not some useless rushed-out-the-door implementation that crashes every step of the way.
