Tried to train a girl on fire preferably for all styles for Pony. The results are quite usable imo. I suggest a weight around ~0.8.
Trained tags:
Main: firegirl
firebody (when the whole body is made of fire, use burning tags in combination)
burning hair, burning eyes, burning legs, burning arms, burning hands, burning breasts
Skin: red skin, orange skin, grey skin, black skin, cracked skin
fire aura
blue fire
glowing eyes, glowing veins
magma belt
convenient censoring
