Can only export as OBJ file?

Hey everyone,
I’m having a problem exporting my rigged model into Unity.

Whenever I try to export it as a .FBX or .3ds file, it distorts the way it’s supposed to look.
On top of that, it’s also flipping the normals on half of the model. The image below shows what I’m referring to.


As you can see, something is going awry, and I’m lost as to what it could be. The image below shows what it’s supposed to look like.


EDITED TO ADD FILE
Support for BlenderArtists.blend (2.29 MB)

I see no demo blend file in your post that can be reviewed

Well, judging based on your screenshot (unfortunately that’s all we have…) the normals on the bend arm are already flipped inside Blender - as indicated by the significantly darker shading in the viewport.

I’ve uploaded the file. Sorry for not doing so earlier.

I appreciate any help you guys can give me.
