I am using standard characters from the UE4 Mannequin and Mixamo Old Pack Support UE4.10 and comparing the current Adobe Fuse! I’m doing all the possible tests … The retarget only works UE4 Mannequin for Mixamo Pack 4.10 if it does with current Adobe Fuse templates do not work and have bone errors!
After several tests with various animations, I conclude that the plugin is not 100% functional with mixamo and what it shows, it works with the skeletons old mixamo models that are only supported with an unreal 4.10 and with animations that do not need root motion. I searched everywhere that the plugin does not say that custom or adobe fuse skeletons do not serve to retarget both UE4 mannequin and old skeleton mixamo to adobe fuse mixamo skeleton new!
Most of the animations in place “slide” backward!
