Can some body tel me haw can i create a cave on unity ? plzz:face_with_spiral_eyes:
Well a cave is - simply said - not different than any other room with walls, a floor and a ceiling. So the easiest way is to use primitive meshes to build that up. That’s not recommended of course - instead you will certainly model that cave in a 3D application and import it as a mesh.
@Glokenbeat thx a lot 
I know this is an old topic. I was playing around with this and figured out a thing or two.
Well there is a terrain exporter script that lets you export terrains as objs. (use the C# version). However it seems to loose its textures. I haven’t figured out how to get the textures from the terrain object. (Note there is also a prefab exporter this cannot be for this method)
After that just re-import and turn the terrain upside down and place it onto of another terrain.
The script is slightly buggy play around with it until you get the desired effects.
After that you need to apply a transparent shader to fake a cave entrance effect along with scripts that temporarily disables collidors so you can go through the wall.
