I directed OL to make two files for one model. In one lamp youd' have the base model which has no properties, a simple model. And the other I'd have the model with the properties, ie: the lamp shade and light. Since I knew both would be tinted yellow I made them Additive's with 255 fx ammount. Then tweaked them as I see fit. Then I changed the fx color (think thats the name of the prop) into a creamy color. Doing that esp helps with black and white additive things, but I'm in a habbit of doing it. For my blue lights I did the same thing as above but did it 3 times. One for the base, one for the blue shade, and one for the yellow light. I believe they all turned out pretty well. Notice while this does not increase rspeeds since its all the same ammount of polygons, it does increase your entity count. So if you have few precious entities left over, I'd suggest compining them into one model and hoping for the best. Good luck.
