Modeling Misc
Mirror All Smartskin
Found under a model's context menu, this feature walks through all Bone Rotate Relationships (Smartskins) on the model, that contain the word "left" or "right" and looks for a matching one on the other side. If it does not exist, it creates it, and mirrors all muscle motion within that relationship. It creates each mirrored key at the matching mirrored position for that bone. If both left and right relationships already exist then it examines whether they have been modified since the last save. If only one has been modified since the last save, then it copies the modified relationship over the top of the non-modified one, mirroring as it copies.
Biased Normals
“Biased Normals”, which exhibit better smooth shading, are now the default spline technique, but old models will still load and animate the same.
