Yes, I have been playing off and on since 0.96 release. Thèse have been done on the OSX version, but I have just set up a Windows version to try Rhino intégration. I am happy with results and I am in the process of doing a comparaison with Flamingo, our standard everyday rendrer.
A few test renders for a bracelet idea. Thèse are just material tests.
I am hoping to spend more time with this program, it has potential.
