Material Thumbnail Display Issue

Hi all. Please see attached screenshot. All thumbnail appear very dark. Same for newly added materials as well. Tried a few things but couldn’t fix it. What’s going on? A little bug? Thanks!

Hello - is the current renderer Rhino render? Can you pleasae run SystemInfo in Rhino and post the results?

Hello I guess the first thing I’d try is disabling ‘Fologram for Rhino’ in Options > Plug-ins folder, then close and reopen Rhino - any different?

-Pascal

Hi Pascal.

I unchecked it, and restarted Rhino. Doesn’t seem to fix the issue. It still shows as loaded though, not sure if that matters. Thanks.

hm… that is unexpected, to me anyway. I’ll see what I can find out.

@xy236 - just making sure - did you disable the plug-in with only one Rhino running, then close Rhino and start a new session?

-Pascal

Thanks Pascal. Yes, I doubled checked that’s what I did. Didn’t help. I wonder if it has anything to do with Rhino’s native material library? I might have modified the folders a bit here and there throughout the project. Maybe that messed things up?

The problem persists in a new Rhino file.
