Where did you get those dev textures you used? It would be nice to have more than orange and grey to work with.
I mean the overall shape, they don't look like mesas, they look like gumdrops. Rock has a grain, like wood, so it tends to have sharper angles.
DARK BLUE = DEADLY WATER The 3 pools NW, SE and middle are not even deep enough to drown a tank ONLY THE MIDDLE NORTH-MIDDLE AND MIDDLE SOUTH-MIDDLE BRIDGES ARE BROAD ENOUGH FOR TANKS. THE OTHER 4 BRIDGES TO MIDDLE ARE INFANTRY ONLY.
Its not hard, I replaced the water with a neon green texture, placed a big neon red cylinder above every refinery and compiled without light so I can see everything. Having max AA on while making the screenshot is a must too. But yeah I could make you such a minimap
