System Information
Win7 x64

Blender Version
Broken: 2.75
Worked: (optional)

Short description of error
When exporting a model that has blendshapes as fbx, the resulting model does not get the correct normals, it only seems to get the normals from the base shape rather than the normals it should get when the blendshape is applied.

Exact steps for others to reproduce the error
For more details and example photos please see here http://forum.unity3d.com/threads/uma-unity-multipurpose-avatar-on-the-asset-store.219175/page-67#post-2281165

Actually, this is not a bug, but rather a TODO (we have no way to access normals from a shape-key currently in Blender, will add that but this does not qualifies as a bug - and cannot be added to master that close of a release).

This problem still seems to be present in 2.78c. Normals of blend shapes still are the ones of the base shape. I tried both in binary and ascii.

Yeah… actually, correct commit now Blender-side is blender/blender@cdd727b7ce (seems like there were some history rewriting :| ).

Re-opened and moved as TODO task.
