Still the same, Arno. I just download the latest development release. I attached the new effect to the light pole then I ->new-> SpotLight attached to the light pole model in MCX. After that I exported and I get MDL together with the new fx file. I compiled the mdl to get bgl and put bgl to the scenery and put the new fx file to Effect folder. No dynamic light there. I also attached the MDL file for you to check.
I've got the dynamic light. I was looking on the wrong pole. The airport is so big and there are 3 types of light pole.
The method is simple. Just put spot light to the model in MCX, then adjust the angle and position to fit the model. Export it and get mdl together with the fx file. Put fx to effect folder and compile mdl to ge bgl and put to scenery folder. You are done!
