Entity Description

Brush-built model that fades out over a specified distance. Useful for creating world detail that doesn't need to be drawn far away, for performance reasons.

 Note: The overhead required by this entity is substantial. Use it only for special effects or when fading very dense geometery, and one could then argue, shouldn't that better be a model?
 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.
