Hi Chosen Few. Thank you for your answer. I was trying to get in the samplebot.dae and even if I when I clicked "skinned weights" I couldn't wear it properly, it was just another lifeless attachment.
There is a "joints" option as well can you bring your own joints? what about the people that have animal avatars that walk in fours or body shapes that are different?
BTW the http://wiki.secondlife.com/wiki/Mesh/Exporting_a_mesh_from_Maya link is empty.
Thanks for your help
