Creating a cave using terrain

I am trying to create a cave environment for an underwater game I'm creating. I created the bottom part but I'm having trouble with the top part. I created a second terrain and moved it above the first but I wasn't able to see it from the bottom. I also tried rotating it using the transform tool but it didn't change. Is there a way to rotate a terrain?

 

No, you cannot use the Unity terrain to create overhangs or roofs, and it appears there is no way to reverse, negative scale, or otherwise invert the terrain.

You could write your own heightmap based mesh deformer that will allow "upside down" heightmaps.

Best way is probably to create your cave systems (minimally, the roofs) in a 3D modeler and then export and place them as meshes in Unity. This is the typical way of doing caves/overhangs on heightmap terrains.

Great advice for making caves here: http://forum.unity3d.com/threads/7791-Hollowed-Mountain

The idea is to put a 'hole' into the terrain and make the cave interiors with a 3d modeling program. It's a good way to get it done!

 

i was thinking of trying to make a cave like in the source engine, the source sdk has a realy nice mesh deformer, good for making hallowed objects or caves as u said, but it will need time so someone could acsualy make the script so the terrain can act like that, or any kind of other object
tho its better to make it in a 3d modeling software but u cannot edit it in unity, u always have to go to the modeling software and edit it, which is rather painfull and takes more time

 

There's a plugin for this on the Asset Store: Terrain Hole System

Description: "This Unity extension lets you make holes in your terrain that characters and other objects can go through."

More information can be found on the forum thread.

 

You need a voxel based terrain set up. There is one on the asset store. Terravol. I bought it last week but we haven't had time to get it into our game yet. My only issues 1. The editing is really lacking but I know I can fix that.. 2.That the mesh that it creates is half the resolution I would like and I don't know how to change that. I was going to drop the dev a note..

 

maybe if one can make another terrain and maybe turn that upside down, then make the hight tool to make moutains that point down, then one will be able to make a cave... or is this not possible in any way?

 

I can just say Cubiquity.

 

There is a new tool in the asset store called digger that lets you make caves, holes, overhangs, etc, really nicely. It's sadly not free though and costs somewhere in the $30 range

 

Unfortunately, within the past few years (presumably) the price of digger has been raised to $70 for the base version and $100 for the pro version.
