So I just bought the trancebot 128x128 set from the torishop.
Where do I go to actually put on the textures?
There isn't anything in my inventory, I didn't get a file, I'm just clueless.
Also additional info, I play on steam.

The market isn't the right place for this kind of thread. Moved to rapid threads.

I don't know if this will actually help or make it even more confusing but here we go:

When referring to textures, there are the physical items themselves which are in your inventory, and the art that can be uploaded onto the texture items.

The full 128x128 set that you just purchased has already come with the trancebot set artwork, and can be found in your active inventory here (under Set:Textures @ the very bottom).

You may visit this page to change your texture art individually, or, you may use the multi-uploader to upload multiple textures simultaneously(assuming that they have the correct file name e.g. head, l_hand, ect.). The multi-uploader can also be used to clear your textures of their art. Do note that your texture items need to be activated in order for you to change the art on them.
