Yes. I followed the tutorial on how to weight all of the avatar bones to a single vertex, as all 26 are needed in the .dae file.. I just redid the process, in case I screwed up the first time.
I'm using 3ds max 2012, however, and I guess the weight tool is bugged? I had an issue where I would try to add a bone to the weight tool and 3ds max refused to select the bone. It's a common issue with 2012, so instead, I took the text method and opened the .dae file in word, then added the bones to the list. I can now select "Skin Weights", but when I do, my mesh becomes giant in the preview window. When I upload it and wear it on my avatar, it's still attached to the avi's hand.
Edit: I downloaded a service pack and it seemed to fix the problem with adding bones to the weight tool.. I'm still unable to upload the mesh with skin weights, and it is still attached to my avatar's hand. I have all of the bones weighted to my mesh correctly. Going to fiddle with it, but still not sure what's wrong..
