A '''brush''' is a piece of geometry you build with the [[Level Editor/Interface#Toolbar|shape tools]] and reshape with the editing tools. Most of a map's walls and floors are brushes. A brush can also play other roles, set in the inspector: an invisible '''clip''', a '''team gate''', a gamemode '''zone''' or an ambient '''sound volume'''.

== Inspector ==
{{Property table start}}
{{Property row|name=Collision Type|type=List|default=STATIC|desc=STATIC is solid and still (the usual). NONE has no collision: players and shots pass through. KINEMATIC and RIGID export as other kinds of physics body and are rarely wanted.}}
{{Property row|name=Collision Layer / Collision Mask|type=Layers|default=1|desc=Which collision layers it is on and collides with. Leave both on layer 1.}}
{{Property row|name=Collision Only|type=Check box|default=Off|desc=Make the brush a '''clip''': invisible in the game, but solid. See below. '''Edit > Toggle Collision Only''' does the same.}}
{{Property row|name=Clip Blocks Hull|type=Check box|default=On|desc=''Clips only.'' Players are blocked by the clip.}}
{{Property row|name=Clip Blocks Hitscan|type=Check box|default=Off|desc=''Clips only.'' Bullets of hitscan weapons stop on the clip.}}
{{Property row|name=Clip Blocks Projectiles|type=Check box|default=Off|desc=''Clips only.'' Rockets, grenades, flames and pellets stop on it.}}
{{Property row|name=Clip Blocks Splash|type=Check box|default=Off|desc=''Clips only.'' Explosions, and the sight lines of sentries, dispensers and the boss, stop on it.}}
{{Property row|name=Weld On Export|type=Check box|default=On|desc=At export, join this brush's visible mesh with the still brushes it touches, so a flush join between them leaves no visible line in the baked lighting. Off keeps it its own mesh. Collision and footstep sounds stay per brush either way. A [[Level Editor/Entities/Group|group]] can turn it off for everything in it.}}
{{Property row|name=Gate Team|type=0 to 2|default=0|desc=Make the brush a '''team gate''' (a spawn door): solid to everyone except that team, which walks straight through. 0 is an ordinary brush, solid to everybody.}}
{{Property row|name=Is Area|type=Check box|default=Off|desc=Make the brush a gamemode '''zone''' instead of solid geometry. Shows the zone settings. See [[Level Editor/Entities/Zone|Zone]].}}
{{Property row|name=Is Sound Volume|type=Check box|default=Off|desc=Make the brush an ambient '''sound volume''' instead of solid geometry. Shows the sound settings. See [[Level Editor/Entities/Sounds#Sound volumes|Sound volumes]]. A brush cannot be both a zone and a sound volume.}}
{{Property row|name=Team Differs Per Side|type=Check box|default=On|desc=''Zones and gates only.'' A [[Level Editor/Entities/Mirror Node|Mirror Node]]'s copy belongs to the other team. Untick it for something both halves share.}}
{{Property table end}}

The brush's materials are set with the [[Level Editor/Panels/Materials|Materials]] tab and the [[Level Editor/Tools/Material Brush|Material Brush]], not in the inspector.

== Collision-only brushes (clips) ==
A clip is a brush you cannot see in the game but that still blocks. Use clips to:
* smooth out collision over detailed geometry (a ramp over stairs, a flat wall over a bumpy one);
* keep players out of places they should not reach (a roof edge, the top of a fence);
* block players but let shots through, or the reverse, with the '''Clip Blocks''' boxes.

Clips draw translucent in the editor; their strength is '''Opacity''' under Collision Brushes in [[Level Editor/Settings|Settings]]. '''View > Show Collision Brushes''' hides them, and '''Edit > Click Through Collision Brushes''' lets you click what is behind them.

== Team gates ==
A gate is usually also collision-only: a spawn door you can see through but only one team can walk through. Set '''Gate Team''' to 1 or 2. Bots of that team path through their own gates; the other team's bots treat it as a wall.
