Hi Alex,
I took a look at the file and here are my investigations. Maybe you will find them helpful. Of course, some of the points mentioned below may had been already tried by you.
• Anything >0.5 for the terminator shadow shift seemed to fix shading artifacts on the model.
• I noticed that the XForm for the model was 1000%. Resetting it and welding vertecies with 0.05mm threshold did fix the problem. Rendered as expected with 0.0 shadow shift.
• There has to be something with the way it was imported/generated/converted in 3ds max, as dashed (hidden) edges are visible in Editable Poly, and for basic shapes, dashed line appear only when retriangulating/turning the edges and then they disappear. For the model you provided, they seemed to not go away/turn invisible in any case (even when converting to Editable Mesh, making some of them visible and some of them not and then converting to Editable poly) and it would be interesting to know how that happened.
• An interesting solution/workaround I found, was turning on NURMS subdivision (just checking it in in Editable Poly) for the model. It does show up bad in the viewport but renders completely fine. Shadow shift is 0.0 in this case as well. If there is a quick/one click solution (like terminator shadow shifting) you are looking for, maybe this can be one.
