Prefab converts your obj file to as3 (after you have flipped it). More As3 3D
than this you will not find :))
so instead of Obj.load("myFile.obj");
you do import PreFabClassFromMyObj and add it to your scene
scene.addChild(new PreFabClassFromMyObj());
sauce = you drop on Prefab --> scale --> revert --> export to as3 --> you
import this class in your project.

Oops, myMesh.invertFaces
