Hi. So when I try to use an animation from a pack I download and put it in a sequencer in the state machine, I get “incompatible skeleton”. While it’s true that the actor’s skeleton comes from a different package, they are both the identical UE 4 skeleton.
If there were differences, you’d have to retarget them, but since they are entirely identical, you should be able to assign the animations a new skeleton.
This is not editable by default, but you should be able to use a workaround by right-clicking on the relevant animations, going to “Asset Actions” and “edit via the property matrix”.
In there should be a field for the skeleton that can be changed.
