I have a desert scene at ground level, I want to build a small Oasis, being a depression in the ground, filled with water,
will then place palm trees etc.

Problem it does not seem possible to make a depression at ground level, I click on TERRAIN then terrain tools/sculpt
editable area/lower terrain and nothing happens. I can only sculpt hills and depressions when the land is above
ground level.

One more question how do you fill small depression, and only the small depression with water.
I have clicked every setting available.

Many thanks for any help.

Simple really, you can't dig into the negatives. ZERO is the lowest number for the terrain mesh, actually made a request and reported that the default value should be raised to avoid users running into this problem.

Guess it is time to send a reminder again.
