Brush Entity

This entity lets you create a stationary piece of geometry in your level which can then be modifed (through its rendering properties) for a number of effects.
Often used for performace reasons, and for things like unbreakable glass, masked textures (fences, ladders).

Attributes

• Name (targetname) - Property used to identify entities.
• Render FX (renderfx) - Gives objects special render effects. Think of it as modifying whatever the Render Mode puts out. The options are as follows:

[list]
[li]0 = Normal

• 1 = Slow Pulse
• 2 = Fast Pulse
• 3 = Slow Wide Pulse
• 4 = Fast Wide Pulse
• 5 = Slow Fade Away
• 6 = Fast Fade Away
• 7 = Slow Become Solid
• 8 = Fast Become Solid
• 9 = Slow Strobe
• 10 = Fast Strobe
• 11 = Faster Strobe
• 12 = Slow Flicker
• 13 = Fast Flicker
• 14 = Constant Glow
• 15 = Distort
• 16 = Hologram (Distort and Fade)[/li]

[li]Render Mode (rendermode) - Controls the type of rendering that is used for an object. Options are:

• 0 = Normal
• 1 = Color
• 2 = Texture
• 3 = Glow
• 4 = Solid
• 5 = Additive[/li]

[li]FX Amount (renderamt)[/li]
[li]FX Color (rendercolor)[/li]
[li]Global Entity Name (globalname)[/li]
[li]ZHLT Lightflags (zhlt_lightflags)[/li]
[li]Light Origin Target (light_origin)[/li]
[li]Minimum light level (_minlight)[/li]
[/list]

Flags

• Not in Deathmatch (2048)

Notes

• Unbreakable windows: Set the Render Mode to Texture, and the FX amount to about 100. This will make the entity see-through.

• Masked textures (blue background, prefixed with "{"): Apply a masked texture, then set the Render mode to Solid and the FX Amount to 255. The blue areas on the texture will not show up in the game.

• Small / complex objects: Brush entities dont break up world brushes (which can cause harsh transitions between light and dark, and performance decreases), so bind small stuff (light fittings, pipe flanges etc.) to func_wall entities.
