Smoothing displacements so they match the surrounding area

So I just started mapping yesterday and I've begun work on a map. In one part of the map there is a slight dip into the ground, a sort of trench you could say. The only problem is that I can't figure out how to make the displacement match the rest of the ground when it connects. I'm sure there's a simple way to do this but I guess I just don't see it. Could someone tell me what I need to do?

Thanks.

Bam.

*Edit*

I think I figured it out, you need to use the "raise to" option.

*Edit #2*

Okay that didn't seem to work, now the edge of the displacement is a little bit higher then the surrounding ground.

Simplest way is to make sure all the edges are lined up before you create the displacement... and then don't move them when you paint geometry.

See Youme's Guide to displacement cliffs for the whole idea of sewing displacements together to make them be as if they were one piece of rock/dirt

The main thing with displacements is to make sure before the brushes are turned into displacements, that they match up. It is also (usually) a good idea that the ground is not sewn to the cliffs, but instead the cliffs go through the ground slightly (this makes some cliff shapes much simpler to create)

Line them up on their sides, so they are the same size on the joined faces, and sew.

I'm sure they are lined up because I made a brush in the ground and just carved it out, and then made the displacement.

Can you explain this a bit more please?

Select both faces in displacement mode, and click Sew button, that will make the edges line up...

because they faces share an edge. As you may have known/guessed, this can be done with other displacements as well.

Ok, I drewed a picture

Nevermind that 2 vertical lines are missing, not important. These 2 share an edge, and they will come together when you press sew, because the edge they share is the same size in units, 192. To put it simply, if you want 2 brushes to sew, make the sides that are being sewn together the same size in units.

Okay, I got it now. Thanks guys. Just one more thing, is it normal to have a very slight gap even after sewing?

No, but somehow it has happened to me as well, even when I had perfectly aligned displacements. Try setting the value to 1 or 0.5 so you can make really tiny adjustments to your displacements and close the gap.

Thats odd, usually doesnt happen to me. I put all my displacements at 2 to start, and increase the scale as I go. I know that having 2 displacements with a different scale would make weird gaps.
