so hypothetically lets say that you need to animate the hair as if its windy outside, you have the character rigged but not the hair, it has hair cards but nothing else, how would you go about animating the hair cards to apear as if its caught in a windy day?

do it in a shader with world position offset, use the UV to control the strength.
Same as grass.

For long hair I rig my polyplanes so it consist of a couple of strand groups controlled by bone chains. I then run custom Verlet based cloth physics on it.
Inserting springs between the strand groups as needed so they don't interpenetrate too much and behave like a volume suspended in fluid.
You can get a lot of precise control with that stuff but like anything hair related setting it up is finicky as all fuck.
I use an algorithm based on the ideas presented in this paper for pic related https://www.cs.cmu.edu/afs/cs/acade
I believe Saints Row IV did the same on certain haircuts.

i don't do real time stuff so i'm just curious if some big brain has figured out how to lerp b/w vertex animation textures and if you could exploit that to fake-sim by moving b/w different VATs.
