In regards to GUI/Content downloading:
I haven't played around with it too much just yet, but I've been working on a mod for a littile while that utilizes RTB's GUI downloading to provide an easy-to-use interface for the clients. However, I've considered adding bitmaps to the GUI to make it look much nicer, which I saw RTB supported sending to the clients. From what I can assume, RTB won't actually download the images the GUI elements refer to if the client doesn't have them (stop me here if I'm wrong on that).
Is there a way to utilize RTB content downloading to ensure that the users download the images? I know I could do it through the default Blockland procedure, but some users have download textures turned off, and as far as I know, there's no easy way to check that server-sided. I already make sure they have GUI downloading enabled in order to join the server, but I now have two questions: First, if I upload a private add-on, despite it being private, are users still able to download the texture files through RTB? Secondly, is there a way to check if the user downloaded content without modifying RTB?
