This was done just for fun/portfolio.
Created in Max with Vray. Base car model was from GM. Damage was done in Max/Zbrush. Wrecking ball and chain parts were textured in 3D Coat. Post in Photoshop. Backplate is stock.
Lot's of work done by my studio associates Jim and Evonne. As always it's a team effort. Thanks also to the crowd at Vray forum for their input.
