func_lod is a brush entity available in all Source games.

It is a bmodel that fades out over a specified distance. Useful for creating world details that don't need to be drawn far away, for performance reasons.

Note:The fading is not always consistent; brushes may suddenly "pop" into view depending on where the player is looking. This happens because of a hardware issues with rendering translucent materials. Low-end cards will fade nearer than the distance specified, and smaller objects fade nearer than a larger object with the same fade distance.

Bug:Weapons from Black Mesa with muzzle dynamic lights causes strange visual bugs when player in End fade radius and out of Start fade radius. Example.

Important:As this entity still counts as an edict, overuse of this entity can be more expensive than simply using func_detail. If the fade-out is necessary, consider converting the geometry to a MDL and using prop_static instead.

Keyvalues

Note:For Keyvalues and Inputs affecting brush rendering, see Brush entity/Rendering related keyvalues and inputs

Name (targetname) <string>[ Edit ]

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

Disappear Distance (DisappearDist) <integer>

Distance at which these brushes should start fading out. The finish fading out distance is value from this property +800, you can change it by setting other value for lod_TransitionDist console variable. Since Left 4 Dead, fading out distance controlled by DisappearMaxDist property.

Min Disappear Distance (DisappearMinDist) <integer> (in all games since )

Distance at which these brushes should start fading out.

Max Disappear Distance (DisappearMaxDist) <integer> (in all games since )

Distance at which these brushes should finish fading out.

Non-solid (Solid) <boolean>

Set whether or not these brushes should collide with other entities.

Note:When using AddOutput, this entity can be only changed from solid to nonsolid, not vice versa.
