Shaded Display mode : Backsurface problem ("Use Front Face Settings" doesn't work)

Hi there,

I just installed the demo version of Rhino 6 on my bootcamped Windows 7 SP1.

I have a problem with the backsurfaces, they are totally transparent eventhough i checked in the options ‘’ Use frontsurface settings". I am just looking so i can visualize both surfaces in same way. Any similar bug encountered with this early release version (Rhino6.3) ? Any solution ?

I precise that i did restart everything after modifying the setings > Didn’t help.
Thanks in advance,

Can you post the result of the Rhino command SystemInfo?

Hi @wim, thanks for your reply.

Here are the info :

My Macbook Pro is 8 years old, still don’t have this problem on Rhino5 .

Rhino 6 uses OpenGL in a completely different way so there’s no sensible way to compare those. From your information, Rhino doesn’t find out about the date of your GPU drivers. Try to update these to current versions for your card.

Thanks @wim for the info. I’ll try to find a way to update that and get back to you if the problem is fixed.

Hi @wim, problem solved by installing up to date driver for my AMD card. Thanks
