Hi Karl
Tried using Phong shading, and it worked pretty good as soon
as I did the "Flatten Normals" thing on the sds. However, I
observed a shading problem when I used a mirrored instance
instead of a mirrored copy of the object; they just didn't
render the same.
This sounds to me like a bug? I even got the difference when
I disabled all the shaders in the material. The scene only
had two distant lights, and maybe the camera flash was active,
not quite sure about this one though. Something to look into?
I can confirm your observations. Errors show up - somewhat
surprisingly - also in ray tracing. Clearly a bug.
Thanks for reporting!
Best regards,
Vesa
