    I placed some displacement in my map and was dismayed to find that I have a leak. I clicked on pointfile to try and find the leak and lo and behold the light is passing right through the middle of my displacement. I convert the displacement into a regular block and viola! The leak is gone! Can anyone help me with this? I'd really like a displacement.

    I dunno why that happens. Normally I just place a nodraw brush behind it.

    Slow down, there's a point of confusion here.

    An entity in your map, which happens to be a light, is leaking. That's a map geometry issue.

    This is not the same as saying that "light is leaking through my displacement", which is a statement of how light-and-shadow are working.

    Displacements never seal the map. You must always put a "real" brush (generally textured with nodraw) to seal your map.

    To use a metaphor: Your map is an air-filled space-station in the inky void of space, and displacements are simply bits of mesh netting strung up around the place for your astronauts to block their view and keep them from bumping into things. They are not air-tight and you you need a good solid bulkhead behind them to seal things.
