| Description | Some of our lights offset the light source from the origin of the light entity.
For example, atdm:lamp_electric_fancy_lit has its origin on the metal base that attaches to the wall, and offsets the light source so it's at the light bulb.
The illumination math determines whether a light is contributing to illumination of an object by tracing from the object to the light's origin. If the light is placed against a wall, it's possible that the trace will hit the wall before it hits the origin, thus concluding that, since walls create shadows, the light entity is NOT contributing to the object's illumination.
The trace should go to the light source, the location that's offset from the light's origin |
