I made a feature request on the official 3dsmax forum for improvements to the new smart chamfer modifier; Evenly distributed edges along the chamfer geometry and inset loops along the borders of the new chamfer geometry.
/!\ Please vote for this improved smart bevel feature request on the official 3dsmax website here: /!\ https://forums.autodesk.com/t5/3ds-max-ideas/smart-bevel-improvements-evenly-distributed-geometry-and-extra/idi-p/14070253 Problem 1: Because Smart bevel uses the edge vertices created by (for instance) the Boolean modifier, there are intersection vertices. These create unevenly distributed (and pinching) geometry that results in shading problems. Blender Mesh Machine Offset Cut for instance does about the same thing, but with evenly distributed edges along the newly created chamfer geometry as do many similar tools like Smooth boolean modifier, Hardmesh and Modo meshfusion.
Problem 2: Ideally there should also be edge loops of 'inset geometry' along the edges of the new chamfer that are perpendicular to the original surrounding geometry. This would result in 2 edges on either side of the new chamfer geometry being perpendicular / flat to the original geometry and would create much better shading.
