Ramp lighting with fsds 3

Howdy. I've made scenery objects (using fsds2). Using the light_landing name has produced flood lights. I'm trying to do the same thing with V3, but the flood light effect does not show. I'vee compiled direct to bgl and via mdl and xml with the same result, no beam. I know there was an issue using the makemdl.exe, but I'm not sure exactly what the cure was. Any sugesstions?Thank,
