I was informed yesterday that the terrain hole functionality was working in Blitzmax, so I did a quick half hour test. This is a feature I find very attractive for level design. The ground cover (small bushes and ferns) is just place holder art, and all the foliage was just "slapped" in for effect. The concept is a simple, hole in the ground which gives access to (eventually) a large underground modular bunker system. A simple hole cover/access/room model was knocked up in 5 mins in 3DWS. The terrain is something I have been working on and have yet to finish.
