Detailed model of a Westland Lynx AH.7 as used by the British Army during the 1980s

Geometry and Rigging

The model consists of 717,862 faces with 740,973 vertices.  There are a total of 50 separate meshes that are parented to a single armature with 40 bones in total.  16 bones are controls that animate the parts of the model and the bones are organised into four groups:

• Doors - with bones to open and close the main doors, open and close the pilot and copilot doors, and open and close the pilot and copilot windows.
• Cockpit - with bones to control the joysticks, the collective levers, the pedals and the windscreen wipers.
• Rotors - with bones to control the main rotor spin, the main rotor angle, the tail rotor spin, and the tail rotor angle.
• Rigging - all the non-control bones.

Materials and Textures

The model is fully UV unwrapped with non-overlapping UVs for each material.  There are three PBR materials - the main fuselage, the interior furniture, and the moving parts (landing gear, rotors etc.) and a simple glass material for the windows.  Each PBR material comes with a base colour, metallic, roughness, normal and ambient occlusion map, and the fuselage also comes with an alpha texture for the transparent parts.  The fuselage textures are 8k and the interior and parts textures are 4k.
