Basically, I’m wondering if something like what BM:S purports to have is doable in gMod with existing models, or perhaps with a custom base model.
Faceposer only goes so far with the standard faces we are all sick of seeing by now. You can shift brows around, pull cheeks in or out, and a few other things, but it would be very hard to actually create entirely unique faces.
Perhaps given a custom head model that was much more deformable than the existing models you could do something like this.
I would be trying to make this myself right now if my gfx card hadn’t burnt out, so if anyone has any ideas about how this could work, or wanted to try to make it, that would be great.
