Can’t remove this artifacts, to whole model was assign noise to bump for more variation of reflections and it’s appear only with bump on, model is high poly even with turbosmooth 3 iteration it’s still visible. Render image will be very high res so it’s visible at 100% zoom. Please advice
It looks more like smoothing (normals) issue rather than shadow terminator.
i just check normals they are fine, here scene if it’s help

I don’t have max 2017 - can’t open your scene.
I don’t know what it was, but reseting transformations of your model, fixed that issue.
Big thanks romullus!
the models was exported from blender via OBJ this is strange though
When in doubt, always reset transforms :]
