I have found that a material like marbel will only come up well if it is rendered in phong mode.
This is similar if i have a metal material. It only renders well while in metal mode.
Can someone explain how to render both metals and stones so as to get the best results.
In R3 and R4 you have [Flat][Gouraud][Phong][Metal]
low-------------------->high Quality
(In MAX there is no Gouraud)
So the settings in the Renderer dialog box are a kind of RESTRICTION. (They are called Shading Limits!!!) In some way you are right when thinking of the buttons as of different renderers. 3DS really uses different rendering codes for Flat,Gouraud and Phong/Metal. But the Metal Shading can render Phong,Gouraud and Flat aswell. The Flat cannot render Gouraud and Phong/Metal, but is much faster...
