Although other formats are provided it is strongly recommended to use this model in 3ds max, due to use of max specific 'LookAt' controller. In 3ds max, model elements are properly linked and animation ready - through system of joints and pistons controllers (with exception of caterpillars).
Model is not suitable for closeups and shots of the cabin interior. It is perfect for visualization of construction sites and mass shots (relatively low number of vertices provides fast render times). It works very well with all kinds of toon shaders.
Elements made from different materials are detached. All objects are named.
Previews were rendered in vray - materials and HDRI are not inluded.
