"Hole" in terrain (caves, cellar,...)

[Bananenfreak]

Hello friends,

is there a possibility to "cut a hole" or something else in a Terrain?
For example I want to set houses with a cellar (dungeon,...); How can I enter the cellar without touching the Terrain?
Another example is a cave. How can I set a static mesh in a Terrain and the Player won´t see a Piece of the Terrain in entry of cave.
Is this possible or only possible with the meshterrain made from lexicon?

Greets,

Banane

Where do you got These informations and the Picture from?
I only found "Google Summer of Code" and a few entries about crashing Terrains...

Volume Rendering has been implemented into OGRE 1.9.0 "Ghadamon". OGRE3D 1.9 was released as stable about two weeks ago.
So, it's possible the next big update of Purebasic will have that version. I'm not sure if Volume Rendering will be implemented into Purebasic, but time will tell.
