Hey guys,

4.2 broke the mouth open as morph feature for fbx exporting.
4.2.1 fixed it, but now my models are exporting with duplicate and broken blendshapes, and it's making unity puke.

My interim fix has been to run the character through blender which automatically renamed the blendshapes, but blender's distorting her geometry a little, which is a less than ideal outcome. This is happening on both standard and extended profiles, but the blendshapes that are duplicated or distorted when this happens are different.

Enclosed is a screenshot, so you can see what's happening on my side.
My suspicion, giving the timing, and the way this problem works, is that this is a bug related to the expression wrinkles that got added in 4.2, or possibly the new lod subdivision updates yall added.

Sidenote: I mentioned this in a past ticket, but export scene has been broken for ages too. It fails every time. And this has happened on multiple pc's.

Thanks.
