I’ve targeted the commander in the a-pose with the epic mannequin rig in the same pose and targeting was successful, the animations all work but there is an issue going on with his mesh deforming the body as soon as he gets animated, the mesh goes out of the proper body shape.
I only have to look in the skeleton editor to see what the issue could be.
From this picture from the skeleton editor I suspect that the deformation is being caused because of missing bones in his Skeleton because there’s only two bones in his arms and in his legs. Hes missing the twist arm bones and the calf twist bones and without them its not enough to get his body mesh into the correct animated natural human shape.
So I gave him to my modeler friend to put in the missing twist bones for me but she is unable to fix
his rig up with Blender because she knows all about Blender but not about Unreal Engine
and because blender has a problem transitioning between the rigs, so I have to come on
here for help to those riggers in here who know how to correct this particular issue to fix up his body.
