Facial Flex Unlocker

This script removes default flex limitations [0.0, 1.0] from Source Filmmaker and allows you to make GMod-like ugly faces.

- You should run this script from embedded python interpreter!
- Not compatible with Source 2 Filmmaker.
- Works with all models that have facial flexes.

Additionally, if you're familiar with Python - invoke main() from sfm_init.py so it will be executed automatically on startup.

Execute this script from the Scripts menu (navbar) every time you restart SFM.

Then, you can move flex sliders in a range of 1.0 for each direction per 1 click. Release the slider and hold it again to escape the limits.
or
Double-click on the flex slider and set any value you want.

- Sometimes SFM stops viewport rendering few frames before fully applying new coefficients if you set exact values by double-clicking the slider. Just move a camera or something else for a second to force rendering.
- Render preview differs from the viewport, but rendered file will look as you expect.
- Flex animations may weirdly flicker in 60fps when the values are too high. This bug is related to frame interpolation and is presented in stock SFM, with bigger flex values it just becomes more noticeable. As reported by the users, it's not happening on some session/animation setups, but exact steps hadn't been found yet.
