Objects are displayed dark and dull in Rhino 8

Hi!

Objects are displayed dark and dull in Rhino 8 for Mac which was not the case in Rhino 7.
Affected are all display modes that are derived from technical drawing and when shadow is enabled.
Without shadow the display is correct.

Display modes based on “Shaded” also do not show this dull effect. But I can not use them because then I have no possibility to enable drawing an outline.

I have added an examle model Test_R8.3dm and two ini files of the display modes that are used:
“Matadorvorlage Boden.ini” and “Matadorvorlage.ini” both are based on “Technical Drawing”.

Screenshots show the effect.

Is there an explanation for this different behavior?
I not no answer to this.

@jeff can you have a look?

It’s most likely an OpenGL vs. Metal (engine) difference… I’ll see if I can reproduce it here, and then determine if anything can be done to tune things up.
