I'm trying to export a model with armature and shape key animations. I've been following this tutorial:


This process works fine for the beak of my character, but not for the eye lids and pupils. The pupils have shape keys to make the character look left and right.

enter image description here

Now I wonder if it's because the beak only has one shape key and the eyes and eyelids have multiple. But so far, the beak is the only one ready to go.

I just need the animations to export into Unity with the shapekeys. Here's my .blend file:

The "F" button is to tell Blender to save a data block even if it has no user, so it appears only when... you have a data block!

In your picture, you have this situation for that eye:

enter image description here

the " + new " button means, there's no data block, and you can add one (an action in that case). Then, the "F" button will appear.


I think that eye has something different than the other...

selecting that green NLA editor stripe, and using TAB it expands, and the " + add " becomes usable, but acts weirdly, at least...

I'm not an expert though, and can't understand how to fix it. But maybe you know what happened to that strip?

  • $\begingroup$ Not really but I spotted something strange in the NLA strips... see the edited answer... maybe someone can spot what's wrong here... $\endgroup$

  • $\begingroup$ Hm. I really wish I understood this better. The long way around would be to recreate the pupils and eyelids and animate them. Really don't want to have to do that, especially for the eyelids. Shape keying those was a pain. Help anyone? Much appreciated. :S $\endgroup$ Oct 11, 2016 at 1:22
