Hammertime: Need a displacement here!

Hello there!

One of the most fun steps in the creation of a map in Hammer is creating terrains, aka displacements. It is also the one that causes most errors, at least in my maps.

CP_Parchis (remember it's just a codename) includes a castle on the top of a mountain, so terrains are essential. Since it is a floating castle, those mountains collide with the edge of the map - the skybox. This usually causes lots of errors. I've been trying to put up with the following problem:

Finding displacement neighbors...
Warning: invalid neighbor connection on displacement near (4.84 3584.00 0.00)
Warning: invalid neighbor connection on displacement near (-64.00 4096.00 0.00)
Warning: invalid neighbor connection on displacement near (2.96 4111.19 143.51)

HammerTime: The CP_Parchis Project

Greetings!

In this new section, Hammer Time, I'm going to talk about my first steps at mapping with Hammer. Hammer, in case you are wondering, is a map editor for the Source Engine (HL2, TF2, CSS, etc), also known as VHE (Valve Hammer Editor). I already had some experience with this tool, although none of my first works is good enough to show it here. I suppose my current project won't be succesful either, but I just want to write about it. So, here we go!
