The game wasn't rigged from the start (Patreon)

My FNIA bear fembot is as rigged as she's going to be.  That square visible at top right of the first pic is her eye target; wherever that thing is, she will always be looking at it.  (In Blender at least.  I am not sure this is how Eye Posing works in Gmod).

In the second image, BEHOLD!  Her eyebrows have their own "bones" so they can be moved around, and I made Shape Keys to give her three or four basic useful mouth positions (for expressivity and acting!!  Nothing else!  None of that!  THAT is right out!)

These are viewport screen captures with armature bones and rotation axes visible because even though I aimed the camera at her, and confirmed that she was in fact visible in the camera view, the render window continued to show absolutely nothing.  I don't know what I'm supposed to do, and this is more complicated than it needs to be.

Also ridiculously complicated will be the process of getting her into Garry's Mod.
