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.
Accurate scaled object.
The turret is a separate object and may be rotated at will.
The tracks are made using the PathDeform tool, the spline path is kept frozen, so they can easily be animated by modifying the percentage.
Three main 1024 x 1024 texture maps.
Main object correctly grouped and named, pivot points correctly placed.
