One of the 3 known entries in the "new medium tank" contest, the winner of which was supposed to replace T-54 as the medium (and, ultimately, main battle) tank in the Soviet Army. This one project was axed the first, as it was probably the most difficult to finish. The complete tank was never built, but at least one simplified armored hull and turret were produced for protection trials.
The model is based on several drawings and some info found by researchers in the archives. Some "artistic license" had to be used, but I think this is rather good representation of how prototype might have looked like circa 1955.
Model done in Maya and rendered in Marmoset toolbag.
Photoshop was used to make textures, xNormal and nDo2 were used aswell.
