Hello everyone!
I started working with someone who created a great hero character mesh for my horror game. He also did the rig using a Blender add-on to create the skeletal mesh I need, based on the Unreal Engine SKM_Quinn mannequin.
Everything looks fine in Blender, but when he sent me the skeletal mesh and I tried to set it up in Unreal Engine, the hands were completely broken when the character is animated. I tried it on versions 5.5, 5.6, and 5.7, but the issue is the same. He says he has always used this add-on technique and has never had any problems with it.
I tried using “Show Retargeting Options” and changing the value from “Animation” to “Animation Relative,” as you can see in the pictures.
It’s seems better at first glance, but it doesn’t solve the original problem and destroys all my animation sequences. So that doesn’t help, but maybe it can help you understand what is happening, because I really don’t.
I hope you can help me, because the mesh looks great, but in this condition it’s not usable right now.
Thank you very much for your time.
