Seems filleted surfaces are not in continuation!
Does this normal?
Subdivision ?

Hi Pilou, circular arc fillets do have continuity with adjacent surfaces, but it's a Tangent/G1 level of continuity. It is normal for tangent continuity to show breaks in reflections. If you want smooth reflection lines, that needs Curvature/G2 continuity and it's not possible to get that with things constructed out of circular arcs like fillets are by default. You could try the fillet option for making a G2 blend type surface for the fillets rather than the regular circular arc fillets.

Nice to see the discussion had grew up even further ... such discussions are very valuable in learning Moi. : - )

Stefan your file works fine, thanks! I need to make further experiments with such filletings however. It is a need for understanding the way Moi works.

Hi Dimitri,

filleting can be problematic sometimes, but the good news is that Michael and MoI users come up with helpful advice on how to solve such problems. :-)

Best regards
Stefan

Even with not so relative little glitches of the Moi Object :)
