Now this is something I like to see in this program.
I do something like this using Poser and Daz3D to make ISO or 2.5 Sprit.
Right now I am rendering out 2D pic to try out in Spriter .
So far Daz3D is working out the best becuse you can tern on and off body part and render each part and save and nameing it for the bone part you just render.
I am hoping that you mite at some point build in suport for 3D for use for BVH this way I can use just one program to build all my Sprit so I am sort of hoping I did reading your post right on 3D.
I'm so freaking ready for this! Super excited, thanks for the updates and hard work! Even more excited to finally be able to get a working implementation setup for Gamemaker
