why does the Blendspace record doesnt work anymore with Mixamo characters?

This is what Mixamo did to my character when I put it in their auto rigger. The mesh looks all wrong, I was told that the tight stiff looking mesh was something to do with the weighting. Because the mesh dosen’t look relaxed or natural, I also set everything to Skeleton on the bones except for the hips. but Mixamo gives no root bone either when you put it through their auto rig. So there’s no twist bones, and no root.

How do I fix this little disaster? Mixamo auto rigger has problems with it. I don’t know if Mixamo put
any weighting on his mesh for The shoulders are all flat and is not natural looking, also this rig has no TWIST BONES in it. The Epic Skeleton have the twist bones in them, probably to allow them to maintain the proper natural human shape during the animations ! There also seems to be a problem with the hips and appear to be twisted and all wonky which throws the body shape all off and this is probably because there’s no root !

As for his uniform, I just chucked any old texture on it for the time being as I don’t have a texture yet for
his top, I also have to find him some shoes.

Look at how far the hips are out !!

How much would it cost to fix up his mesh so he can finally be Unreal Engine ready. I don’t care about him being Mixamo Ready because hes not ready for Unreal Engine with his mesh and hips looking like
this. I’m tired of messing about with Mixamo’s Auto Rigger because I’m not getting good results because of missing bones they not putting in their auto system since they withdrew Unreal Support is causing issues in Unreal Engine when you go to animate these meshes. They look bad.
