Hi, sorry, in retrospect mixed up the two ways of doing it because I tried both approaches.
Approach 1: place origin at world origin, rotate and inverse translate the object for every frame.
Approach 2: place origin at pivot, translate object to the proper position and then just rotate it for each frame.
So my ani files were approach 2 and my meshes were from approach 1, sorry about that.
