I’m trying to import a new head to another model with the scene merge option for Max, which already has bones as well as has already been skinned. I need to do this because the original head which belonged to the lower body had bad skinning done and the new one has much better skinning, and it’s also the same head as the old one. However, when I’m done attaching the vertexes of the new head to the old body and ready to add weights from the older bones to the new head (upper spine bone to influence the neck area of the new head), the vertexes of the new head move to the feet of the character, presumably following the pivot point of the head. I already tried moving the pivot points of the neck bone as well as the new head meshes but they still do this.
Is there any way I can fix this or do I need to remove the skinning from the new head, add the new bones and the required older bones and start over?
