Hey,
I have a character with different blend shape emotions, however only one and specific will export to fbx format.
Others will be visible in fbx, but changing number/slider won't affect skin at all. In Maya it works perfectly.

I tried:

Exporting only one blend shape (one of that did not work) - doesn't work.
Exporting all in different order, redoing blend shapes with history cleaned out.
Reinstalling FBX.
Tried out on 2016 Maya version (I use student 2015)
Deleting History, non-deformer history. Exporting and importing skin maps.
Unlocking normals

Non of those worked.

Any ideas what is this?
