Model Import

Importing a model

A:M's splines are in most cases superior to triangles or straight polygons. However, trying to import a polygon-based model poses its own challenges.

3DS

(Source) If you have 3ds MAX, Import it into there first, highlight the whole model and right click - convert to - editable poly.

Then go to Geometry and select quadrify all.

Export as an .obj and select Quads in the exporter

Import in to A:M and while you'll have to fix parts it shouldn't need anywhere near as much as it would if you'd imported a .3ds made of triangles.
