Whoa, that's fascinating, sounds like it could lead to a tremendous render speed improvement.  To be clear, would this be added to/phased in with the existing Carrara render engine, or is it it's own render engine that would need to be added to Carrara?  If it can simply be added to the existing rendering engine, seems like that would be a bit of a task but if it is a whole new rendering engine that would be much more of a task (as it would have to be programmed to recognize and render the existing Carrara shader system).

If the render speeds were significantly improved for Carrara 9, that would definitely be a selling point.  If we're talking gigantic speed increases (you mentioned in the other thread it could be as much as 2000% increase, that seems overly optimistic but who knows) then it would make Carrara 9 upgrade a must.
