Distorted reflections 2004-11-15 - By Stuart

Hi Tom,
Just tried your suggestion on my objects made from imported shapes and seems
to work. Painting the top face Faceted restored the proper reflections. Now
why should this be an issue with beveling an object made from an extruded
imported curve but not a TS made curve?
Regards
Stuart

Hi Stuart,
I would try painting the flat face with Faceted rather than Auto-Faceted
material. My guess is that the bevel takes the angle between the flat face
and the beveled edges into the auto-faceting threshold, and the renderer
then tries to calculate how that face curves, trying to smooth it into the
bevel. Of course, with lots of points around the edge, it tries to smooth
the face in different directions, and the result is distorted reflections.
You could try to find an Auto-Facet angle that keeps the flat look of the
face and the curves of the bevel, but if your shape is pretty simple, I
would opt to just paint the face that should be flat with the Faceted
material as the quickest solution. It's the same result too - the only
reason for using Auto Faceted with different settings would be if you have
lots of faces similarly affected and it would be time consuming to paint
them all Faceted.
HTH!
