How to lower the terrain?

[WALP]

When you create a terrain it will be spawned at level zero I think. When you create a terrain you define how tall/low it can be.

The solution to this is to up the terrain to around the center or where you find convenient depending on how much up/down height you need.

The best tool I know for doing this, is the flatten brush. Select it, make sure settings are at their most powerful(no falloff, big harness, big rings etc.). Then input the level you want the terrain at, and start painting until a big enough area for your needs has been upped.

In my case I had a terrain that was 50 tall, so I flattened it to 25.
