Making Terrain

Hey, I’m pretty new to source mapping, and I’ve run into a good problem when using Hammer. I’m trying to make a larger map that will be quite open, but I’m not sure how to make the terrain. Here’s my problem summed up:
-If I use one brush for the entire map, using displacements on it will look shit-terrible because of it’s size.
-I tried using multiple brushes and sewing them, however that did not work very well.
-The map is going to be huge scale, and I want it to look good.

So, what’s the best way to make terrain on a large scale? Otherwise, what other ways are there to making it? I’m not getting the trick to it, I guess.

Use about four displacement brushes with a power of three. The edges of the displacement grid need to be perfectly aligned for sewing to work.

The correct way is lots of smaller displacements, why didn’t it work well for you?

I must’ve just been sloppy. I’ll try again and see if it works.


Here’s a question. I have two brushes that are both 512 units in width. When I try to sew them, however, they don’t do anything. They’re perfectly in line. Here’s a pic.


Make sure the two displacements (The terrain) are the same size when sewing.
