XPlane2Blender's material model is different from Blender's. In XPlane2Blender, all Blender objects must have a material. If you have multiple materials, only the first one is chosen. A material can have any number of texture slots that do the majority of the work changing how an OBJ looks in X-Plane.
Due to some inconveniences of Blender's data model, some UI elements will be shown even if using them would result in an invalid OBJ or would have no affect.
Link- The data-model linkage of the material must be set to "Data". If you have materials that are linked by "Object", it is recommended to remove them to keep things neat
These settings are used to decide when and how to draw the material.
The alpha channel of the albedo (day texture) will be used to create translucent rendering.
Export Versionmust be at least "11.0x"
Surface Behavior settings control how this material interacts with X-Plane in non-visual ways.
Day-Night Preview Balance- This setting provides a convenient way to preview the material in Blender's 3D View. To enable the Day-Night Preview feature, add an albedo texture (uses Diffuse->Color) and a night texture (uses Shading->Emit) to the material. Adjusting this slider sliding this will automatically adjust their preview in the 3D Viewer. It does not change the content of exported OBJs.
These settings can only apply to
