Holy Cliffs

[citoria]

So I read the cliff tutorial, and some stuff by steam wiki, and I though I had it down. I made 2 intersecting walls, carved a tunnel, game them walls with no draw texture on the back and then selectem them all for displacement and everything was going fine. But then I noticed the nodraw backing was gone, and I get this happening on my cliffs.

Now when I was using the paint geometry all the walls were selected to I thought it would connect them all, but I guess not. Any idea what I am doing wrong?

you gotta select each displacement using the texture selecting tool (shift+A) and then go to the displacement tab and hit "sew" that will bring all your displacement neatly together at the edges

and the nodraw thing is supposed to happen btw

so I hit sew before I do any actually diplacement painting?

Are the connected like the wiki says?

Also be careful: even with auto-sew hammer screws up sometimes. So you just have to watch out. Displacements are a real bitch

 

[poopster101]

you can do it after you do your displacement painting

As long as each side of the displacements match in size and have touching edges (or half sizes) they will sew. Bring up the face-edit window, select the select option, select the displacements you want to sew (I use the 3d view, hold down the control key to select multiple displacements), then hit the sew button. If they don't sew, the edges don't match . Zoom in on grid 1 and check to make sure your edges match up perfectly in the 2d view (as it shows the origin faces). If you have transformed the dissplacement (stretch/skew/rotate) chances are it didnt land on an even grid and it may need to be resized to snap into a grid. That way, the displacement you are trying to sew to it will now match on grid.

Tip: if you made a nice displacement already and you know the edges can be sew if they would just connect. Set your painter to Raise to XXX amount and the size of brush to 1. Then paint X, Y and Z along the edges of the 2 displacements. You will ruin some of your work, but they will align.

You're saying that displacements have to have the same height and width on the edge that touches or they will not sew? I have steered clear of diplacements for this reason. I have been unable to sew any displacements I have created therefore I try to stay away from them.

That's correct, you've got to have your displacement edges match in size. If the edge of one is 1024 units high, the one next to it has to be 1024 (or half of that, or 1/4) in order to sew properly. The verticies on one edge need to match the other, or it won't work.

Hmm... I think all the displacement guides I've seen have left that part out.

mine has that in.....

Not to knock your wonderful guide but...

Now I crunch the front displacement into where the tunnel ends and I crunch the second set of points in the tunnel forwards. Once they are close to each other I select the whole lot and hit that handy 'sew' button

You're miss reading it in context

by that point I'd already mentioned about all the displacements having shared edges, what you highlighted is saying is that I don't worry about keeping them aligned whilst working on them because I can hit sew afterwards (because they already line up) and it smooths it out.
