Why not? You'll have to program it of course. That's not something Crystal Space does as it is only the 3D engine.
First I wanna thank you for the greetings. I really am glad to be able to communicate here.
However I would like to pick your brain a bit. As far as I'm concerned, or understand, 3d realms are composed of several different areas, but it's really only one "solid" mass. I'm not sure then how to approach this division. Would I compose the land of different 3d plates, or do we just program the hex as an overlay of the landmass? Any other approaches to this issue that you can think of?
