Hello everyone! I have finished rigging the avatar, it is one piece nothing is split up. I tried uploading the avatar to Secondlife with firestorm, but the upload with skin weights tab wasn't available to check, after reading up a few fixed I found that I need 26 bones rather than the 19 that avastar has (From what I have seen in my Dae file by opening it with Notepad++) So I changed the value from 19 to 26 and added the bones to the list of the other mbones. Then, I tried to upload that same DAE file, the upload with skin weights was checkable, so I selected it and tried to calculate upload fees but unfortionately as I was calculating the fees I got an error, saying my mesh had Zero bones? I figured it was because the bones I added in the DAE file (Via TXT) did not exist in the 3d version, So I went into avastar and selected the (Show extra) option, Which revealed the skull, eyes & toe bones. I exported that version and now the upload with skin weights is not checkable anymore, Please help this problem is getting rather irritating!
