For all the minimap examples on here I can't find one that does quite what I want. I can't get it happening via the blend modes example either.
My primary focus is just to overlap a map in the corner of the screen.
The map is a separate file that looks like a map (only green and a bit transparent so it looks like a scan, but that's probably irrelevant) The aim is not to show the whole map but just show further away, so I just want to be able to take a large graphic (the map) and only show a circular cutout of it and have the rest transparent. This minimap is going to turn and move as the player does so a the static map examples are not enough.
TLDR; How do you only show a circular piece of a graphic and hide all the rest? (Is it possible? All the minimap examples I find all seem to be static)
