Unfortunatelly I am not a max user. So I cannot tell about it. In Lightwave I could just do a extrusion with a tool like "bevel", "extend" or "Smooth shift" but don't move the newly created vertices. This creates new edges and thus breaks the smoothing there.
I don't know it that is something similar like "chamfer" in 3ds max.
Another option would be to cut the group of polygons by unwielding the edges around it.
But auotmatic wielding all vertices might destroy smoothing methods like mentioned above.
A "smoothing group" sounds like magic but it will be something very simple at the end.

If 3ds Max displays the smoothing groups correctly then it also has to convert it to DirectX and OpenGL through cutting meshes on the fly.
yes, meshes in modelers are stored in much more complicated data structures and for viewport rendering they get converted to what opengl needs all the time but game engines don't do it that way because it's much slower.

By the way: If you split meshes then you get open meshes and althogh you got hard edges you lose the chance to use stencil shadows at the same time since stencil shadows need closed meshes.
usually there is a separate data structure for boundary information so you could have stencil shadows nevertheless. i am not sure how this works with gamestudio but stencil shadows aren't the future anyway. they have too many disadvantages.

I thought eventually smoothing groups all boil down to the creation or splitting of extra vertices to create the smoothness, and the "tool" of smoothing groups simply automated the process, rather than creating them all by hand?
yes, that's how it works!

That is a good hint of you, Ventilator. If I create a LOD version of a model with closed geometry then I can use an open mesh object for visual rendering while the stencil shadow uses the closed-mesh-LOD-stage of it.
This improves the visual effect and speeds up rendering time of stencil shadows.
