I have “Child of” constraints in my model (for props that character is using)
When I link the character to other scene, I lose bone offsets- bones jump to their constrained parent bone and I have to re-set the positions. is there any workaround for this?
When using the NLA, make sure you turn off the ‘Offs’ button on every parentless bone.
Regarding the first problem: for the bones in question, are they in the source rig, and if so, are they in proxy-protected layers (i.e. armature layer has ‘dot’ drawn on it)?
