Hoot.
This item contains versions of Stella 3D model for Source Filmmaker and Blender. SFM version has hardware morph (HWM) automatic facial flex correctors for better control, and Blender version has a custom Rigify setup with eye trackers and HWM controls implemented as drivers for shape keys.
Note that this is a NSFW release, so if you're uncomfortable with it, don't buy it.
Stella SFM version without HWM controls is also available for free at SFMLab:
