Displacement setup

Just looking at some Valve maps for reference - when they create their displacement ramps, they use an individual brush for each side. When I've been creating mine, I've been using a single, solid brush and making each visible side of this brush, a displacement.

Does anyone know of any particular reason why they're using this method? I can't seem to find a benefit to it except to prevent displacement brushes overlapping solid, visblocking brushes - which hasn't been causing problems in my own work.

Well, I wouldn't say it's less mess in a map, as it's a new brush each displacement = more clutter on screen ;) But having converted to this method, there are many benefits revealing themselves, especially when it comes to tunnel creation and such. Manipulation and achieving specific goals has become far easier.

I think in most cases I prefer using multiple faces on a brush. Fewer brushes on screen. No welding, etc...

However it's easier to destroy/recreate/change a displacement if there aren't more than one face used.
Say the top displace is fine but you want more divisions on the vetical face. You have to use seperate displacements.
Or if the top is fine but you want a fresh start on the vert. If they are seperate you just destroy/recreate the vert displace only.

You can modify a single face of a multi-face displacement, so I'm not sure what you are getting at there.

I use multi-face displacements whenever I can to keep things clean, because if I do need them on seperate brushes, they can be split with the clipping tool. Regardless of where the displacement verticies have been moved to, clipping directly to the edge of the brush between the displacements will separate them cleanly as if they were single-face all along.
