Hello I have similar problem here.
I would like to see in incoming Unreal Engine 5 easier method for import assigned animations from Skeletal Mesh to another (second) Skeletal Mesh.
Basically why animation files doesn’t exist?
Instead we need add manually animations data to single character in Blender,3dsMax before import to Unreal.
It’s really frustrating I hope that UE5 would be better and functional than UE4.
