Looks like you may be using a ‘Set Master Pose Component’ in your construction script. If you plug the Metahuman head into that node, it will do this. Looks funny like that. This is because you’re setting a master pose form another animation blueprint. Try disconnecting that (if that is the case), then parenting the head to the skeleton (whichever component you plugged into the ‘New Master Bone Component’ in the Construction script), connecting it to the ‘head’ socket, then rotating it -90 degress on the y axis.
Hopefully this makes sense and I haven’t gone way off course!
