How to copy rig & model then animate it with different animation

So i linked a model and it’s rig (Rigify) to another file and animated it (let’s call rig-A). i want to link the same model & rig to the same file and same scene but with different animation (let’s call it rig-B).

so i linked it > relations > make proxy to the rig.

the problem:
after i make proxy for rig-B, rig-A is back to T-pose, and if i pose rig-B, rig-A is following rig-B pose

anyone know the solution?

Ahh. Just save and rename your source file with a different name and link that for your second one if you have no more changes to make. Alternatively append the second one. Or another solution is to duplicate the original one in the source file and link that one. I don’t have a lot of information about what you are doing so I’m not sure if these will work for you. Version 2.81 of Blender does have library overrides. I tried it and on simple characters anyway it worked sort of. But you might want to still use proxies.
