But then why do I feel like such a moron for having to ask it? Don't do a lot of work in Bryce, but I like to play... working on a desert scene, and I want rolling dunes in the background. Seems easy enough... generate a terain using the Rounded Dunes fractal. Sure. It doesn't have EDGES! The dunes are cut in half and I can see under the damn thing! I am just not getting something here. Mountatins are easy, the come down to the ground plain. But this is making me crazy, and no where have I heen able to find this mentioned --- that's why I am feeling like a moron. Everyone has had to face it at one point or another, right? TIA Evil

Can you post an example of the problem?

paint out the edges of the side toward the camera so they come all the way down to the bottom of the terrain--ie, paint black over the dunes that are cut in half. You may have to work at it a bit so it looks natural

or you could experiment with the square, round, and guassian edges. Try setting the terrain to solid, at least you won't be able to see under it anymore. I find that clicking square edges, holding down the button, and dragging to the left makes pretty good edge that, even though square, only looks so from above and looks fine from ground level.

Or, simply do what I do! You see, there's no need to fix a problem if no one can see it anyhow. Have a problem with edges? Hide the edges! Here's how it all plays out. Your terrain looks something like in shot number one, with edges flared out. Problem is(as in shot 2) you can see strait under it, which makes a big ol' mess of things. One way to fix this is simply take the edges out of your viewing. Using the Camera controls, zoom in close to the terrain. I expand the thing, making it considerably larger, till the edges just float out of your field of view, but the big(or small) dunes or whatever they may be are still all over the place. Also make sure you cover the Horizon line with the Terrain, or something else, otherwise it wont look quite right. But, of course, its all up to you, so if you think it works, go for it. Thats about it, and I hope I've solved your problem.

I usually tile things like dune squares and plop the camera smack bang in the middle of it. Same as what Sparr says, only my way, you have a larger terrain to work with. Catlin

What works for me on those kinda things is a combination of hiding the edge behind other objects or else tilt the terrain somewhat so you can hide it under the ground. Often that will work great too to hide the edge and at a distance you don't even notice that the terrain is tilting towards the camera

Set the terrain to Solid in the terrain editor.

Use the zoom - drag so it fills the whole square then click the fractal button.

Or enlarge the terrain and move it to the camera.
