Shadow Intensity % - Resets to 0 when 'Options' command is run

Took me a while to figure out what is happening here… but watch the GIF. When I run the ‘Options’ command, it resets the’ Shadow Intensity %’ to 0.

Is this a bug, or is there something I am doing wrong?

Thanks, I’ll check it.
@rjohnson1 - can you please export that display mode and post it?

Small update: I did find it only happens when you click on the shadows ‘tab’.

hm - I cannot repeat this so far - is this behavior consistent in any file?

Can you please run the SystemInfo command in Rhino and copy/paste the results here…

ok, so now i feel dumb…I had the same issue in another file (via file>open), but when I closed Rhino and reopened Rhino, it works now. If it happens again I’ll reply.

but here is the contents of the SystemInfo before I restarted Rhino:

I’ve seen a restart clear cobwebs before - thanks for the update. If you see this with any regularity, you might try, as a test, disabling the Lumion plug-ins in Options > Plug-ins page then closing and reopening Rhino - see if you can work for a while without this occurring.
