Hey. How can I make a cave that has a higher ceiling than the regular height of the wall piece?

Sorry for a noobish question.

I'm not sure I understand what you mean, I guess you could up the scale size to get bigger tunnels and place rocks along the sides to make them narrow.

Well. Basically I wanna be able to create a room that is really high. In the CK a wall isnt that high, and I can't put one wall on top of another one, so there must be some other way.

They do have pieces that are just walls, not the prefab wall/floor/cieling. Using those, boulders, pillars, cliffs and such you could probably make some decent caverns. Resizing and rotating objects may give you more unique pieces so the area doesn't seem repetative.

Don't scale kit pieces if you can help it! The snapping will break at most scale sizes, and as you make them larger the textures will appear to get lower-res because they're being stretched over too much surface area.

There are "Epic" cave pieces available which are used to create some of the very large caverns in the game. For situations where even those aren't big enough, you can use piecemeal wall sections and even mountain pieces, as seen in Shriekwind Bastion. Keep experimenting - just don't scale anything that works on a snap, or you'll likely regret it down the road.

If the epic cave walls arent big enough for you, use the "wall up" pieces. For instance 'CaveGEWall01' goes on top of 'CaveGEWallUp01' to make it higher.
