Hi Arno, when i import an Api File there have lights then i can see the position and what colour he has. But, after i make a MDL File and import with Creator to make a BGL File.....there are no lights in FSX to see ! Why ??? Thanks a lot regards ULI Ps. I make all my Objects with EOD, that is a perfect tool to make API Files. I big Tower with buildings is ready at 20 minutes with all what we need ! And in this tool we can give the Obejects all FS2002 lights. Blink fast, normal , slow or what we need. And in Modellconverter we can see...but no show lights at FSX.
