Terrain Dynamic Lighting Export

I love DA, and use it for pretty much all my battlemaps. That said, there's a feature that I'd like to suggest/request. On the VTT's, such as foundry and roll20, the dynamic lighting works awesome with the structures/rooms.

It would be nice to be able to set a certain height within DA for the dynamic lighting to be calculated from. This would allow us to easily dynamic-light caves, canyons, rocks, trees, etc.

I'm not familiar with DA's coding, but what I'm suggesting could be like taking one altitude layer of a topographic map, and simply tracing those lines.

Just something I was thinking would be nice, as it takes a long time doing the dynamic lighting for "Badlands => Mesa" areas and such.
