Does the CSG_Active really make it movable or is that just a mappers wired setting?

It leaves a white brush when people copy the working brush into a new map.

[Hellkeeper]

Yeah, this is a ghost version of the red brush. No effect on anything.

Yeah, this is a ghost version of the red brush. No effect on anything.

All though, the thing that I question is if it's not used or unused, why is there a color selected for the brush. White.

So is a white brush like white light and has all brushes in it at once ?

[sektor2111]

In a variant of MH-LongCorridor rebuilding map returned some ugly HOM effects - after deleting those white junks everything returned to normal. Let me see... those are results of COPY-PASTE habits + 3 LevelInfo Actors were sitting there... White Junks are pointing BAD mapping practices. Usually I'm removing polys even from red builder brush because that data has no purpose at all.

[Red_Fist]

They can be used to walk in like a subtract.

I just copied then pasted from the red brush over and over, in the same test map,
If you paste a bunch, they ALL will produce a subtract area independently of each other.

If you paste several, whatever you do to the red brush makes all the other ones change the same way, all at once.
If you copy and paste the white ones they don't get affected all at once.
But they are impractical, in that, using the regular brushes is much easier, but I fussed around with them.
Must be some temp holder for the red brush, or something it uses as a temp brush in memory.
