reflections break on the fillet

[hitch_cg]

Hi everybody,

I wonder how you achieve smooth transitions of reflections on fillets. When I render, the reflections always break on the edges of fillets. Now, I understand that this is due to the fact that Rhino builds the fillet as a new surface that is different from either of the two adjoining mother surfaces, as is shown by zebra here.

I've tried all possible ways, such as Fillet, Blend, etc. with minimizing the tolerance, units, mesh etc. and I still have this problem.

Thank you!

you can ask to rhino newsgroup a betterway of modelling it.
you did a blendsrf?

and everything is joined together without nakededges ?

I already asked in the official newsgroup, they suggested BlendEdge or BlendSrf, but it doesn't work. Just try it yourself - blend or fillet two surfaces and see the reflection break.

Of course, there are no loose edges, everything is joined together.

send me your file... but all this for this little piece...

its been that way forever when using fillet. Its because fillet creates another surface. So the end result is 3 polysurfaces each with their own unique UV's.

If it was a must. remodel this piece using a revolve for the center cylinder and a sweep of a staple shape for the wings with a cap. This would produce the proper relfections in the wings and on top of the center. FilletEdge = one of the worst commands mcneel has ever given us.

It has nothing to do with joining edges, or the fact that it is a different surface. It has all to do with the kind of transition. Traditionally, a filletedge creates a circular fillet and therefore a G1 transition. If you want to create a more lifelike transition, you need to replace this filletedge with a surface blend with G2 (curvature) continuity. In Rhino4 you can even create G3 and G4 transitions. I think the G3 continuity is what you want to see on your object.

My hint: try to get more infos about G1,G2 and G3 surfaces. PowerFillet from Npower support all types of fillets. ( a demo is available)
BlendSurface is a good way to, because you can select the surface blend type G2 and G3: tangency and curvature.

My english is not good enough to explain more about G1 .. G3.

Thanks everybody, I'll dig into G1...G4 more.

yeah a good MacPro G5 would do the job too.
