Yeah but it isn't really possible, you'll need to train one on your own I guess.
I'm currently doing it and its extremely time consuming.
You will need to split all images and stuff and make it into folders, define each image for what it is.
Like for Retro Warrior.
Retro Warrior, walking north, east, west, south
Retro Warrior, idle north, east, west, south
or like..
I don't think its gonna be any free model like this for a looooooooooooong time.
