Hi Arno,BINGO !As I have two hard discs, I searched for a BGLC and found it in Airport for Windows 2.6. Copied and tested successfully.. a new xyz.bgl was made. On the scenery the light was only shown at dusk and night time. Yahoe !Now I have to configure (placing on the right place) the light. Question: may I attach the light triangles to the lamppost ? I know that the triangles may only be linked together. Because I have several lamppost to place. Perhaps I better make an API... and that's another challenge, h

Hi Jos

Hi,Thanks for this info. I check for duplicates too.Greetz. Jos

Hi Arno and Firestriker,Thanks for the help (see also "FSRegen configurations"). Have now set a range of self made lightpoles along the apron. They cast a light upon the tarmac at dusk and night time.This is of course the beginning... a long way to go. But this is the light in the darkness of GMAX... lol.Greetz. Jos
