hi, my question is:
how can i get custom body textures ONLY in singleplayer.....of course without buying them!
i have put all the textures by their exact names in my "toricant" directory!!!
but they still does not appear in game......

Create a new folder named 'Test'. Put there the textures you want to try with their correct names.Then, in the chat box of the game, type /lp 0 Test or /lp 1 Test.

You can't do that with yourself because the game automatically downloads your real items and textures when it starts.
