Animation Retargeting failed w/ Blender|ManuelBastioniLAB Skeletal mesh

So i have a skeletal mesh of a humanoid character i exported after creating it with the ManuelBastionLAB addon for blender. I tried skeleton retargeting to get my character going with the Unreal Engine 4 AnimStarterPack and all goes fine up until i try to Retarget an animation. When i do this happens.

At one point i did get the “Approx Size” to tone down to around 5000x etc. (which is bad) but i never got the animations to work properly. It always scales my characters to heavens and above for some reason. I had the same problem with APEX cloth a while back and i hope that i won’t be stuck on this as long as back then.

Hello please watch my video listed below. The problem is your bone scaling. I’ve had this many times before and in the video I cover how to fix it.

Been away from the forum for quite a while, sorry about that. I followed your instructions and it did fix it somewhat, apart from the fingers being horribly twisted, which happens (probably) due to there being 4 finger bones on the MBLab skeletons and UE_Mannequin having only 3. I finally somewhat fixed it (not really, i only escaped the problem) by exporting straight from MakeHuman and downloading a T-Pose for the Mannequin. That imported it (almost right) I did fix an issue with clavicles being far too widely apart via your method. So thank you.
