    Is there a secret to this? Some of them just wont line up, creating tiny gaps. I've tried smoothing w/ both displacements selected but there's still a hole.

    Thanks.

    A picture is worth a thousand words.

    It happens when I took the initial displacement, made a copy of it, and clipped copies of the copy to make a door way in it.

    If it texture the nodraw brush behind it with the mountain texture, it looks ok but I don't want a bandaid fix.

    Are you making sure the brushes you make them from are either of equal length or a half, quarter, eighth etc? If you make one face say 1.3 times the size of the other the nodes of the mesh won't line up so you can't sew it.

    Yeah. Take into consideration the wireframe of the displacement's vertices when it's selected. This stumped me for a while despite being pretty obvious.

    Displacements sew to one another via their vertices, so if you have two displacements at different powers or one a tad more stretched/squished than the other, they won't correspond properly. Clip your brush up to match it or change the displacement power.

    I don't think he knows about sewing.

    Select your displacements and hit the sew button in the displacement edit window.

    Different powers are ok, everything can deal with that. The only sewing requirement is that edges are either equal, or one is exactly half the other (and lined up from one end to the middle.. not 1/4 to 3/4 or something :p).

    As said above +

    There are 2 ways to sew.

    1-select all displacements to sew (must be properly aligned) and hit the sew button

    or

    2-select all displacements to sew, click the auto-sew button, then paint some geometry (at which time properly aligned displacements will auto-sew).

    It's possible you are working at a grid size of 1, in which case it's very easy to have misaligned verts that look aligned unless you zoom in REAL close.

    Work at a high grid size with displacements.
