In the next update to WW I am removing the light calculation that is the Multiplier Value times the VMF Exporter light multiplier if the light has a WW Entity custom attribute applied. The feature was originally needed because WW did not initially have native entities, and it was necessary to control light values via native lights.
The light multipliers will still be used moving forward if the light does not have a WW Entity. If it has a WW Entity, the updated Entity definitions will include a brightness spinner.
This change should eliminate a lot of confusion people have had with lights.
I'm also adding some functions into the WW Pro entities for manipulating orientation via classic Hammer angles.
