How do I re-link an (accidentally) ‘unlinked’ Level Sequence back to the original Animation Sequence? BTW “Undo” does not work with Unlikned Level Sequences.
Hey, I had the same issue, but I found a solution:
In the animation sequence, in the asset details tab, under animation → advanced, you need to add an item to the list called “asset user data” and then select “anim sequence level sequence link”
Now, if you go to the control rig in the level, the actor might have a red symbol. if this is the case, just right click the actor symbol and go to “assign actor” and then you need to select the corresponding control rig actor in your level.
I have also added a screenshot of all this below.
EDIT: This is not really working for me anymore after testing it again. Further research needed.
