Here is an experiment I've done for making maps in Blender
From a map supplied by our GM, I made scenery in Blender that sorta matched it using building models from opengameart ( cc-0 ) and some buildings I made for 3d printing for modern micro-armor ( 6mm) wargaming.
I figured all I had to do was render it from the top, down and it should be good
Clearly I need to learn how to texture scenery and lighting better ( I'm okay with modeling though )
