I received many questions these days regarding of the hair retextures.
I currently am using a different method, which consists in creating a new hair from the original.
This means, that you can have both original and retexture.
But, one can not please everyone, not everyone like to have both.
So, I will now, add an alternative version to those hairs to be default replacement, meaning they will replace only the original.
Unfortunately, by doing so, the package size will increase a lot.
So, be sure you always merge your packages to increase performance on your game!
