This exhibition orginaly modeled in Rhinoceros but then i export it to 3Dsmax for vray and material. You can easily change the color of each part by a few click ( i make it easy in material editor) it is Vray-ready,all the textures and materials are set, just open the max file and hit the render button.

This model seperated by polygon, it means you can apply any color in any software and it doesnt need UV mapping.

File included: .Max (2016) .FBX .OBJ .3DS Keyshot file
