Name- This is the name of the layer and ultimately the file name of the OBJ. When empty and in "Layers" export mode, the name "layer_x" is automatically applied, where x is the layer number. When empty and in "Root Object" export mode, the root object's name will become the layer name. If the name is a relative path, the exporter will automatically create the folders necessary.
Type- The type of X-Plane OBJ being exporter. This greatly changes what options are available and the behavior of the exporter.
Autodetect Textures| On | Turns on or off autodetecting an OBJ's textures from Blender's material's texture slots. When unchecked, text fields will appear and you will be able to manually specify which textures should be used. Beware: Some material and textures validations will be turned off! In addition, Composite Normal-Textures will be ignored for this layer.|
Autodetect Texturesis turned off, and any of these file paths is left blank.
Cast Shadow (Global).
Tilted|Off| When checked, X-Plane rotates the object before placing square on the ground even when the ground is a slope, as opposed to placing as if it were flat relative to gravity|
Required Surface|"Any"|Requires X-Plane to place this OBJ on only certain kinds of surfaces: "Dry", such as land or "Wet", such as oceans, rivers, and lakes, or "Any" for either of them|
Slung-Load Weight- A float indicating the weight in pounds the object is. 0 by default. It is used by physic engine for things carried (and possibly dropped) by planes.
Export- A checkbox which determines whether or not the layer is exported. On by default. Only useful to turn off when you want to debug a scenery object by not having it there.
Debug- A checkbox which determines whether or not the layer will emit debug information. On by default. The debug information will only show up if the Scene Settings'
Debugis also on. Turning this off will have no affect on OBJ performance.
Add Export Path Directiveis pressed, a new Export Path directive slot is added. When the x-mark on the directive is clicked, it is removed. Empty export path directives are skipped.
