Thanks! I am glad you liked it
The materials in the scene are all corona mtl.
I used to assigned material in Modo so that way it is much easier to reassign the right materials in 3dsmax.
I do that to maintain some materials in objects that have more than the two materials. So instead of select each polygon in 3dsmax for assign a material I use the selection that I did previous in Modo. That works really fine and is pretty fast. :)
I used only Corona sun + sky + Corona lights in this scene.
