How do I import this mesh in parts without it deforming?

Hrm, I can’t seem to get my bones to distort like that on import myself, but the bones I have here are from a previous rig of mine and I already applied all transforms. Are the bones all there and the mesh just not in the correct location?

I’ll just run through my export process and we’ll see if there’s any differences at base.

(back up your rig/model/anims first)

So first I select the armature and hit ctrl+a to open the apply transforms menu and select apply transforms

Then I’ll go on to export. You can ignore the transforms area since that’s dependent on how your object is facing and your workflow. (Ignore the box, I hadn’t worked on clothing yet so it’s box fashion week).

On to the import:

Everything came in clean:
