info_lighting

info_lighting is an internal point entity available in all Source games. It can be used to change the lighting origin of a prop_static or a vehicle prop. Set the prop's lightingorigin keyvalue to point at this entity to make the prop light as if it was at the info_lighting's origin. Good for prop_static entities that are embedded in world geometry (like rocks/windows/etc). It also changes the cubemap origin, meaning the prop will show reflections from the closest cubemap to the info_lighting entity, regardless of if per-vertex lighting is enabled. For dynamic models such as prop_dynamic, use info_target.

Important:(in all games since ) Lighting using info_lighting is not compatible with per-vertex lighting (-StaticPropLighting). If a prop_static is compatible with per-vertex lighting, disablevertexlighting must be set to 1 (yes) for info_lighting to affect lighting (it will still affect cubemaps).

Tip:Since this entity only counts towards VBSP entity limits and not in-game entity limits, it can still be useful for adjusting the lighting position of a prop in Hammer++, since the lighting preview doesn't preview per-vertex lighting.

Note:This is an internal entity. When the map is compiled by VBSP, it is processed and then removed; it does not exist when the map is running.
