I made a custom portrait model, and I would like to put a custom light on it so that it looks more awesome.
The lighting sets that already exist in the editor work just well; I switched lightings in Art: Lighting section of the portrait model and they appear with the model with no problem. However, after I modified their specifications(Ambient color, Diffuse color, etc) via the Lighting window and launched the game, the portrait appears with the map's default lighting, as if it does not recognize the modified light applied specifically to it. I created a new light set copied from existing ones, but it doesn't work either.
How can I modify existing lights and properly apply them to portrait models?
