- How would one create new flexers entirely?
- They are based on Paul Ekman's Facial Action Coding System(Wikipedia). Basically you can make every facial expression with flex(or Action Unit) combination. And that combination is stored in an expression file. If your model implements these flexes(by keyshape animations), you can share facial expressions with other HL2 models.
I'm not sure why you want to create entirely new flex set, anyway I think it's possible. See
facerules_xsi.qcidefine flexes and their controllers. - N-neko
Deleting expressions folder
I wasn't aware I'd done any work with expressions yet while doing my (placeholder) choreography. But I've got a 32 Mb "expressions" folder in my mod folder. What would happen if I deleted the folder? Can I do it without anything breaking, or is it a necessary part of making my choreography work? --Giles 16:04, 4 Sep 2006 (PDT)
- It's full of thumbnails for the stock phoneme expressions (a silly system, but there you go). If you delete it the thumbs would be recreated when you next played a synched WAV back. --TomEdwards 00:52, 5 Sep 2006 (PDT)
