Oh, yes, importable gradients are definitely a thing! And aw, now I really wish I could give you a texture randomizer - I've been trying to program a better version so I could share it with others, but the current version is pretty much only usable for me, as it assumes a certain folder structure. This type of program isn't difficult to make even for beginning programmers though so if you happen to know any geeks with some extra time on their hands, you could ask them, and if not, I should probably be less lazy with that improved version. It really is a nifty little program in the end :)

Thanks for reading and commenting, I'm glad you enjoyed the tutorial!
