I have SDS in Carrara, I use it pretty regularly on Poser figures by now, I just whack into the vertex modeller and I can choose any material and give it SDS smoothing. Great feature, and I can adjust how many levels of smoothing I want it to have. I just wish I had something like Studio inside Carrara... that would be a perfect little world for me. Actually Studio's bones work quite similar to Carrara bones, its just more advanced than Carrara. Ah, here's hoping to the next version of the program. At least Eovia is close to releasing the Poser plugin.
