Yay another question right away xD
So you all know there Maps in which you are in a small region and when you e.g. enter a circle of power you move to another region and not only the camera bounds but also the minimap changes only to this region.
But the Camera-Set Camera Bounds trigger only limits your sight to the region -
so how do you also change the minimap?
You can't unless you're very inventive. Use the search tool and read some of the recent threads about it; I believe there have been 2 in the last month.
First, create an all-black 256x256 TGA file with an opaque alpha channel. Then, import it into your map with the file path "War3MapMap.tga". Remember to remove the "war3mapimported\" before the path.
