I can't find any Velvette 3D model for port it
But... I exported a Minecraft skin of her to import her into the game
A personal skin because Velvette is my favorite character from Hazbin Hotel, I've always wanted a 3D model of her to port it to San Andreas.

So you can play as the 'Backbone of the Vees' as a Minecraft skin in GTA SA, I hope you like this skin.
