Weird looking faces when importing from Blender

Question

Hi,

I'm trying to implement facial animations using Blender Shape Keys in Unity. Right now they're being imported Ok, but for some reason, after adding a few Shape Keys the face of the model started to look weird when reimporting. Is not like they're missing but they don't look good anyway.

I've checked my model for normal issues but they're all pointing outside as seen in the attachment.

Have t$$anonymous$$s ever happened to you? I'm newbie to Unity but not to Blender and t$$anonymous$$s is starting to become a problem since I can't t$$anonymous$$nk of somet$$anonymous$$ng that could have caused t$$anonymous$$s.

Hi, you can see with enabled normals you have got double faces. In blender click W>Remove doubles, to be sure normals are ok, you can click CTRL+N in edit mode to recalculate normals.

Hi Kamil1064, thanks for you answer. I did what you say before posting the question but I had no luck. There're normals inside the character's mouse because there are intended faces there which builds the internal mouth.

I finally solved this by following a "hack" that bypasses what seems to be a Blender FBX exporter bug: scaling the model up to 5x, applying the scale and then scaling it back to 1x without applying. That's it.
