This 3985 challenger locomotive was a real challenge for me...detailed to the core,everything right to the nuts bolts wires are modelled...every part of the engine is carefully modelled and extremely detailed to facilitate close up renders...everything you see in the thumbnails is geometry no bump maps have been used... everything is properly aligned and modelled proportionally download and view the large preview files just to get the idea that how much detailing has been done a lot of reference material has been used....light set up is not included
