Here’s what I’m thinking. 2 options
Have a table of textures, each texture should have an offset to the previous texture, so that when iterated they look like a video. Have a loop go through the images and the result would be a video of the textures on the hair.
Option 2:
Same thing as option 1 but with meshes being iterated and not textures ( which would look like actual hair moving )
I prefer option 1 for performance compared to option 2.
