How do you round off polygons in 3ds max 5 so then a complicated yet box shaped object (so it is four sided) can have a slight spherical shape to it? For example I am creating a pokemon type monster for a game project that has a fairly complicated shaped bone helmet with horns. I created this helmet by extruding a spine. Currently this helmet is just 4 sided so it looks flat but I want to round the whole helmet off so there are no edges at all. If you don''t exactly understand what I''m trying to explain then I must apologise. But the effect that I want is kinda hard to explain. Any help or advice would be very helpful.
