Challenger 2 with Theatre Entry Standard armour package. British main battle tank.Modelled to a 1:1 scale of the real thing.Rigged for use in Blender but has partial rig functionality in the other listed softwares.

Blender Rig:

• Tracks and wheels set up using four empties (two for each side) using transformation constraints that can be adjusted to calibrate rotation speeds and add more range.
• Transform limitations set on controls for more convenient animation and to avoid inproper animation.

.FBX files include the materials from Blender but these may have to be checked if imported into another program. When importing to other programs, the diffuse and roughness seem to be set up fine, but I had to set up the bump and metallic in the materials manually.
