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.
