I checked out the post describing how to add lights by the attachment method in FSDS3.5.1. Difference here is, I am attempting to attach lighting to objects, e.g., towers and light standards, using a similar method. So far it hasn't worked - I think the problem lies in that the attachpoint "blurb" as it's been called, needs to be copied into the compiler to work. As scenery is compiled using BGLcomp, I am unsure how to go about adding the code in there. Any help is most welcome.
