Well the doubt is i have my own set of textures, but i cant use them how??

when i start toribash my character appears with the set but a few seconds later it dissapears

how it can be?

You need to buy the texture items themselves here and not just place the pictures into your toribash folder.

Buy the textures then upload them and you'll be able to see them in game, too.

Also others will be able to see them, too.
