Simple question about leaks.

[_Meitsi_]

Simple question: Do displacements seal leaks?

 

[Limpet]

Nope.
Only world brushes

And, though displacements are recognized as world brushes by Hammer, they're taken out of the world by BSP before leak testing is performed.

Just place a nodraw textured brush under it to seal your map up

Oooo
Didn't know that.

Yep, "Double sealed" the displacement areas, and working ok.

Another question popped into my mind:
How "cheap" are brushes fully covered with nodraw? If I hace loads of them covering leaky areas and that could be done better with less of the "nodraw brushes" is it worth remaking the areas?

 

[Sgt. Redneck]

Nodraw is verrrrry cheap, because it isn't just a transparent texture, the compiler actually literally puts nothing there as a texture, so it is verrrrrrry cheap.

Nodraw will still create clip planes and cut up world geometry and VIS leaves, though.
