I am working on a scene to establish geometry for conversion to OpenSCAD.

I'm super close, but when I zoomed in to closely inspect how things were
positioned, I noticed that some objects simply weren't being properly lit.
Adding emission only partially remedied the situation.

The objects are all just a simple torus {} with plain rgb pigments.
But for some reason the yellow torus is the only one really affected.
Lights are just point lights.
Lit from the front with no obvious occlusion.
Adding a top light doesn't help.

The shadows are really weird too.

3.8 beta 2

Any ideas?
