func_null
is a brush entity available in
Mapbase. It is a brush version of of info_null
. This can be used for creating texlights that don't have a visible brush in-game, such as for prop-based lights or accentuating lighting coming in from a window.
Because this entity isn't removed on compile, it still counts toward the edict limit for a split second until removed on map spawn.
Code:This entity uses the same C++ class as info_null. As such, the same behavior can be achieved in any game simply by manually setting a brush entity's classname to info_null.
Bug:Hammer will strip brushes from entities which are defined in the FGD as point entities. It also does not allow a point entity and brush entity to share the same classname, as it will only use the most recently defined version.
Alternatively, add an func_null FGD entry to base.fgd; it will spit out an error in the console when loading the map, but will otherwise be ignored by the game. This can be renamed to info_null using
TeamSpen's Hammer Addons's comp_kv_setter
or a hex editor.
