General

Can I use Ortho4XP and simHeaven?

Yes. Ortho4XP provides an updated bash mesh (the 3-dimension surface) and texture layer (the orthophotos you see) and simHeaven provides an updated objects (buildings, trees, etc.) as an overlay. In fact, it's ideal to run both together since the simHeaven object placement is based on real world data so it should mostly match the orthophoto imagery.

Issues

Why does there appear to be a gap or shadow between the land and water?

This happens if custom_overlay_src is not set to the X-Plane 12 Global Scenery directory or if it set, the tile with the issue is likely in an area where the Earth nav data is in the X-Plane 12 Demo Areas directory. In the latter case, the custom_overlay_src_alternate can be set to the X-Plane 12 Demo Areas such that if the Earth nav data is not found in the custom_overlay_src directory, the custom_overlay_src_alternate directory is searched.

Why are there some "bumpy" runways?

This is likely caused by an issue with the OSM data resulting in the airfield not being appropriately flattened. To fix this, encode its boundary as a closed way on OSM (don’t forget to add the tag ”aeroway”=”aerodrome”, then (optional but recommended) one tag for its name and one for its ICAO code). Pay attention to reuse as much as possible existing OSM nodes, and to close the way.

Why is one of the tiles completely filled with water?

There is likely an incorrectly tagged feature in OSM as a coastline in an area where it does not exist. To fix this, you can manually open the OSM coastline file in the JOSM application, delete the incorrectly placed coastline and re-build the tile. The OSM coastline file is located in Ortho4XP/OSM_data/tile_folder/specific_tile/*_coastline.osm.bz2. To prevent issues for future users, you should also submit a change to OSM.

Why do some of my orthophotos have white squares?

This is due to a server issue of the orthophoto provider. Delete the cached orthophotos by opening the Tile collection and management window, select the tile having issues (double click to make it the active tile), select the "Jpeg imagery" option under "Erase cached data" and click "Delete". Alternatively, browse to the Ortho4XP/Orthophotos directory (this is located in the _internal folder for users running the packaged version of Ortho4XP) and delete the tile folder. Rebuild the tile and the orthophoto will be redownloaded.
