Hello!
Everytime I open a Rhino file (I always work in shaded mode) all the surfaces appear dark.
I have to change the mode to rendered and back to shaded and the problem gets fixed.
Attaching screenshots before and after I do the shaded>rendered>shaded fix.
I’m running the latest version of Rhino, but i’ve had this problem in previous versions as well.
Thank you in advance
Yiannis

Thanks, Yiannis -
On paper, that looks fine.
Just to be clear… When you start a new file from a factory-default template and create a simple box. Put the perspective viewport in the factory-default Shaded display mode. Save and close the file. When you then launch Rhino and open that file, do all surfaces appear dark?
-wim
With factory-default Shaded display mode, No it doesn’t happen. With my customised Shaded display mode it happens always.
Trying these steps I found out that the problem occurs when the shaded display mode’s Lighting method is set to ambient occlusion or scene lighting, and the Use advanced GPU lighting in checked. Going shaded>rendered>shaded still fixes the problem every time.
Still, I prefer to set it to ambient occlusion, because it doesn’t distort the surface colors as much (highlights-shadows) and although it’s similar to no lighting, the overall brightness is adjustable.
Can you export and send your shaded mode so we can have a look?

I can reproduce the behavior here.
RH-84129 Display mode does not load correctly
Thank you Gijs, Wim, for looking into it.
Have a pleasant week!
I’ll fix this…but it seems somewhat contradicting to have Ambient Occlusion ON but then also have Shadows OFF… What’s the point? Why not just set the lighting scheme to “No Lighting”?
