This tool is used to trace the number of static and dynamic lights that light the selected object.
Ptero-Engine II does not support SW lighting, i.e. it needs to use a video card with HW lighting support. A single object can be lit by the maximum of 8 lights at a time. The static lights are drawn with higher priority. Because of this, it might happen that in a scene lit with a large number of static lights, a flashlight does not work in certain locations. This tool serves to track down the objects that might be lit by too many lights and fix the problem.
