Detailed model of a Westland Sea King HC.4 as used by the Royal Navy for troop transport (the Royal Air Force search and rescue HAR.3, Royal Navy search and rescue HAR.5, and Royal Navy airborne early warning ASaC7 versions are also available separately).

Geometry and Rigging

The model consists of 609,461 faces with 622,597 vertices. There are four separate meshes (main fuselage, exterior parts, interior parts, and lights and glass elements) on a single armature with 68 bones in total.

16 control bones allow animation of the undercarriage, camera pod, rotors, and the cockpit controls. There are also 3 pre-rigged controls that animate the windscreen wipers and the two doors opening and closing.

(See the linked YouTube video for more details)

Note: The rigged controls are only available in the native Blender format, the armature should work in the .fbx, .glb, and .usd formats but some of the constraints may not.

Materials and Textures

Each of the four meshes has a separate material fully UV unwrapped with non-overlapping UVs for each material. Each PBR materials comes with colour, metallic, roughness, normal, and ambient occlusion texture maps; the lights and glass material also includes transparency and emission maps. The fuselage colour and normal maps are 8k, the other maps for the fuselage, exterior parts, and interior parts are 4k, all the lights and glass textures are 1k.

The materials were designed and created in Blender for use with Cycles but the should work in any renderer that supports the PBR metallic workflow.

Note: The textures may not connect properly when using any of the import formats, but the textures are suitably named so they should be easy to reconnect if necessary.
