Welcome! This document will point you toward useful resources for creating X-Plane scenery.
If you are not trying to create scenery for X-Plane, but you are looking for tech support, most of the information you need is here:http://www.x-plane.com/contact.html
Please note: if you are having trouble installing X-Plane or the flight simulator simply does not work at all on your machine, please email or telephone tech support; do not file a bug report.
This website (http://scenery.x-plane.com/) contains information, documentation, tools, sample code, and tutorials for authors who are creating custom scenery for X-Plane 8 and programmers who are writing utilities for X-Plane 8 scenery:
We have a moderated yahoo mailing list, x-plane-scenery. The purpose of this mailing list is to give scenery authors a place to discuss technical issues regarding the creation of scenery. The group home page has both a "join" button (if you have a Yahoo ID) and mailing addresses to join the group without a Yahoo ID.
X-Plane.org has web-based forums, including a forum dedicated to scenery creation.
The X-Plane Scenery Website contains a listing of newly released tools and documentation on its front page. If you use an RSS/Atom reader or your web browser supports RSS or live bookmarks, you can subscribe to this feed to automatically receive news on new tools and documentation.
Usually a new tools announcement is also sent to the x-plane-scenery mailing list.
The xplane-news mailing list is another moderated Yahoo mailing list, used to announce new versions of X-Plane.
Sergio and Ben also have a blog with notes on the scenery system.
