I know this is asked many times probably (even recently), but I haven't figured out a comfortable way to create the polygon hair with cards.
Here's the low poly head (separated from the rest of the body) from my character where I'm trying to create the hair on top of it:
I'm aiming for a ponytail hairstyle like this, but with a shorted ponytail though:
As you can see, I've painted a basic hair colour on top of the scalp in case that player could see the coloured hairline between the possible hair strands, instead of the plain scalp with a skin colour.
Also, the alpha planes/cards for eyelashes are way more easier
than styling and modelig the hair itself. Kinda stuck where to start and go with.
