Model created in 3D Studio Max 2009 and converted in multiple formats. All formats include materials and texture maps. The Max format uses mental ray materials and render. There's no need for a third party plugin or anything else, just drop your model in the scene and hit render.
The turret is a separate object and may be rotated at will.
The Cromwell A27M, or Cruiser tank, was one of the most successful series of cruiser tanks fielded by Britain in World War II. It was the first tank in the British arsenal to combine a dual-purpose gun, high speed, and reasonable armour all in one balanced package. Its design formed the basis of the Comet tank.
All objects are grouped and named according to their real functions. The turret acts as a separated object and may be rotated at will. The tracks are made with PathDeform so, in the .max file they can easily be animated.
