It is possible to sculpt Caves by using the normal map editor? or I just to make entities by placing over another?





Another is can I make an underground system and remove the water when I shape the map when I click RMB?

Unfortunately, the answer to both questions is no, not at this time, but I believe it has been confirmed that water will be removable in the future, along with several more options for water as well. There is no cave or tunnel system in place as of yet, and I'm not aware of any confirmation that there will be. You can make a cave entity and place it in your scene, in fact, someone already has one in the free model section (or third party models) that you can download, and it looks pretty good! Edit: I just confirmed the cave is in the free model section, near the top of the threads, it's made by Rolfy. Get it while it's hot! He's an awesome modeler/artist!
