So I know it is possible to make certain parts of the model of a character by making the texture transparent than in brawl Box change the texture type to either C18 or RGB5A3. But I tried one of my hacks in game and the parts I tried to make transparent just showed up black, but in Brawl Box they showed up transparnet, even when I used both types if textures

So I was hoping someone could help shed some light on this for me. I remember back from the days with ASH there were +1 textures which could be made transparent, like link's sword. So I used to the type of texture as that but still showed up black in-game D:
