A volume that emits an ambient light within the volume. No shadows obviously since there is no source for the light (Maybe a toggleable directional setting?). Its purpose is purely just to set the ambient lighting within a given volume, potentially also with a setting to override the natural ambient lighting in a condo so one could even use the light volume to make an area pitch black dark.
Also the light volume would have a toggle on whether or not to allow lighting from other sources to exist within the light volume, such a lamp inside/nearby the light volume adding onto the light volume’s ambient lighting.
This would be especially helpful in square shaped rooms where we don’t want our lights to bleed into other rooms, but still want an entire room lit up without having to enable shadows- which often doesn’t do the job anyways.
This would be really good for performance as well as rendering ambient lighting for rooms- which I imagine a lot of people would take advantage of in order to fill a room with a preferred lighting- is less intensive than rendering directional lighting. Condos already have ambient lighting as is, this just gives players control over that ambient lighting in a given area.
