It has a lot of new features, including PyroCluster (ala, Afterburn) and fR Scatter (Vray charges extra for VRay scatter and it’s IR), but the IR is very buggy at the moment…lots of crashes. I was initially able to build a pyroclastic group of clouds and tweak their look with the IPR without any crashing, but at other times I couldn’t get anything going with it.
I don’t think Cebas understands the value of this feature…I think they just threw it in because people like me have been bugging them to death about it over the past few years.
If they thought it was an important feature, they’d have some demo videos and such up on their main page.
Nevertheless, it boasts a very robust OpenEXR and render pass management system. In fact, Autodesk just licensed the OpenEXR implementation in their subscription release. Lots of elements that would formerly have to get it’s own render pass are now additional channels in a single EXR file.
I have had no trouble with the regular renderer, and it does seem a bit faster. It’s just the bugginess of the IPR. Cebas is catching hell over it at the old forums, so hopefully they will get on it and release a Service Pack/ bugfix soon.
