Muscles doesnt work in the avatar creation...

Already Read all Unity info about exporting to FXB, so i go to maya and export an FXB (2013,2012,2011 versions).

Unity gets nice and easy the files, in the bones adjustments I just need to press force TPOSE and im all Green lighted and the file structure of the avatar seems to be perfect.

When y pres MUSCLES buttom, I now enter to my doom (muscles FAIL). The bones looks like crouched but the mesh seems like T POSE and dont caring about the bones…

Im kind of a RTFM guy, but already read them at least twise, looked at youtube and no help there neither…

Some one has a little advice?

I think you need to recreate the rig for the model in Maya or Blender.

The Rig its done already in Maya, and this process worked once with one character, but now for some reason it doesnt…
