The latest version of WorldEditor, the scenery editing software for X-Plane, is now available! This is the first version that supports the features that are new to X-Plane 11, such as service vehicle routes. You can now search the hierarchy pane, view line, forest, or polygon files in the preview pane, and get a text document of any validation errors. Of course, it also includes better validation and tons of bug fixes.
As it is still in early beta testing, you can't use this version to upload airports to the Gateway, to keep buggy scenery out of the database. You can get a copy of WorldEditor 1.6b1 here, and report any bugs on the Gateway Bug Reporter page.
