So if you create a character using the Character Object then it allows you to not only scale the character but scale it with keyframe animation (must use Object tool to scale)…for this reason l went through all of Bret Bay’s old Tuts on Cineversity in regards to making your own Character Template cos l needed a rig with no feet.
BUT…to do the scaling the skin deformer’s Type under it’s object tab has to be set LINEAR…with spherical the mesh just gets killed.
Sorry if this is well known…but thought it might help cos l couldn’t find anything obvious in the manual stating this.
