Hi!
Is there any way to create high-detail GUIs in 640x480 res? (i.e. not just a scaled-up 320x240 res GUI)
Yes, just use sprites imported to 640x480 res. You are though only able to move them on a grid of 2 pixel squares, but they show up as they should in both, the editor and the game.
That is the same question I made in Beginners What is the max size of GUI? Because my game is set to 640x400 but the Gui editor make w320 x h200 always. :)
