I have come across Alrot's nice Hs/Bae125 and am finding a workaround to the same FSX landing light issue that he came across. So, Alrot, I kindly ask for your assistance here, as you have found a way around the same problem! Specifically, this concerns the landing light created with a semi-transparent poly (as seen from outside the aircraft and in VC mode). On my own model, I cannot get the part to be invisible during daytime. I have added a variety of conditions to the xml_parts file in the Makemdl folder, with varying results, none satisfactory. Wondering if you would mind sharing the .xml code used in your HS project Alrot, I would really appreciate any help you may provide.

Thanks for the quick response and the info. I was looking for the second link above, as it had been read before, but was unable to track it down since.
