So, using MCX, made a scenery BGL out of a bunch of models, for instance..took a berm and made 12 different length models. Edited them, re-named each one and changed GUID number. Some other models were compiled from several merged models. Compiled the scenery BGL. Everything shows up perfect in MCX. Go to place models in FSX with Instant Scenery 3, the models don't show up at all. Not a base model lacking textures, but zero, absolutely nothing but a red box around where the models perimeter box is. Kind of stumped with this one. Never came up before. Any ideas?
