Game engines that easily allow caves and overhangs?
Posted 03 August 2011 - 06:49 AM
I have created a topic before asking about game engines that allow voxel terrains. It appeared that there aren't many. Well, what about game engines that can create caves and overhangs easily and are available for indie developers? Are there any? All i want is to create very large terrain with vegetation, rocks and big amount of overhangs and caves.
Thanks for your answers upfront!:happy:

You're looking for an engine that natively allows you to create cliffs and caves as part of the terrain. Some engines have this feature (voxel terrain), but most engines still use a heightmap-based technique.
So, if you want a cave in most game engines, you model it in a 3rd party modelling program (3ds max, blender, ..), and then you import this into your engine and place it on/in the terrain.
If you wouldn't mind using this last method, I would suggest you look up "modular" modelling, to save you a lot of time.

Because, most commonly, terrain in 3D games are handled as a flat mesh to which a heightmap is applied. A single heightmap does not allow you to specify caves, overhangs, or other similar structures.
You can use multiple heightmaps, if your engine knows how to work with them. To simplify, one map bumps "up and down" and the next ones bumps "out/in". These maps are relatively trickier to generate or work with.
Depending on the game world, you can model the whole terrain, or you can model certain parts of it and "overlay" it with your heightmapped terrain.
Rarer techniques are voxel-based engines or procedural/higher-order surfaces based engines. But, those are not common.
