First post here woo! So basically I have a character rig linked in a new scene, and the custom properties I set up as drivers are greyed out and un-keyable in the new scene. The custom attributes are on the bones of the rig, I’ve had a look on this forum for similar problems but can’t seem to see anyone!
Hoping it’s a simple fix, using 3.0 btw so let me know if there’s something else I should be doing.
Okay, so after a (very) quick google, I found the answer on the blender stack exchange
The library overridable should be ticked on any property that you want to be edited (keyed) in the new linked scene.
