The texture of this 3D model of a Klemm L25d VIIR LX-MA airplane was created using the BPR render settings in Sketchfab.
We used three main settings: specular, color and glossiness.
We set up a light scene with three white sources of different intensity for better reflection of the PBR
The best way to get the highest quality texture of a large object like this would be to use photogrammetry. You would need to take many photos around the object from all different angles. The light should be set evenly on the entire object in order to avoid shadows and to get good texture. Then the photos should be aligned in photogrammetry software like Reality Capture or Agisoft. After that, all you need to do is align the textured model with the geometry captured by Artec Ray.
