But that has modeling penalty though. I'm used breaking my objects when needed in the modeling workflow only, and I tend doing that simple and clear as much as possible. I don't like having a huge amount of objects in my 3d files. Breaking the object generally happens because of using separate texture files (one for each object), sometimes because of animation script issues, a few times I did that for lighting purposes. But there's no reasonable cause for breaking an object in many pieces just because I need different crease angle transition values inside the very same model. Doing that is not that big of a problem if the model is low-poly, it becomes a tremendous waste of time (and makes the modeling phase a turture) when dealing with medium/high-poly objects where a savy usage of crease angles makes a big diff. Anyway it looks like it's an .AC file format limitaion. I looked inside an .ac file, the crease property pertains to the object level, not to face level. I definetely need to switch to another 3d file format. New OSG FGFS supports new file formats, right? Who does have any experience with those ones? Would someone help and get me a few hints about using OSG specific 3d models? I'm interested in the new OSG environment anyway.
