1st question back is : Where did the Model originate?
To answer your question: Yes it has happened to me and others. It does depend on the source model on what needs to be corrected to solve the issue.
If it originated in DAZ, for instance, make sure all clothing/parts are parented to the base model.

Hello all and thanks in advance!
I have been able to map bones in 3dXchange to 4 models from an artist, however the 5th is giving me an error message: "All mapped bones must be under the hip bone."
It seems that because of this I can't select the Convert button. Also for some reason I can't map the eyes.
Anyone else had this issue?
Thanks very much.
