How-to | Create 3D Files for Quantum4D

3D Studio Max

1. Before your export, be sure that your geometry is made up of proper triangles and quad polygons, and that the face normals are pointed in the correct direction.
2. With your model open in 3DS MAX (using generic units as the world unit), scale your objects (using uniform scale) so that they now fit within a 2 x 2 unit square, centered on the 0,0,0 axis, and be sure that it is oriented towards the FRONT viewport and that you are working in the FRONT viewport.
3. Now select your objects and go to UTILITIES tab, and click “Reset XForm”, then click the “Reset Selected” button which appears.  Now right-click on your selected objects in the viewport and choose “convert to Editable Mesh” from the popup menu.
4. Whether your scene is only one object, or several objects, select all your objects and click the HIERARCHY tab on the interface, then click the AFFECT PIVOT ONLY button.  The button will now be blue, and you can go to the bottom of the interface framing and type in 0,0,0 for the XYZ coordinates respectively.  Be sure that the mode of the type-in is set to “Absolute Mode Transfer Type-In”.
5. All your objects should now have their local pivot points centered to the world, and you can re-click the “Affect Pivot Only” button to de-activate this mode.
6. Now proceed to export using File>Export, then choose OBJ, and be sure that “Flip YZ-axis” is checked, as well as “Normals” and “Smoothing groups”.  Scale 1.0 should work fine, as well as Faces set to “Polygons”.  All the other options are not necessary.
