Requesting for help again Hi all forum members. Here I am again, requesting for your advice. Well I'm still with this delayed project of Necochea airfield in Argentina. The fact is that the project is almost finished. I finally animated the hangar doors and used VTP polys for the ground to look nicer. But there's still one thing I have problems with, the trees. I added trees with Rwy12 and I can see them in my computer but some friends that had tested the scenery told me that they couldn't see the trees. I understand that a library-object BGL must be included inside the Scenery directory, so that is what I've done. But the problem is still there. What can you advice me? Which are the most suitable trees to add to a scenery? Thanks for your time!
