Sun doesn't work in viewport

Hello,

I have a problem with sun in viewport.

When I check the sun on, nothing happen. I still have the random sun moving while a move in my viewport. I would like to make sun studies and modifying the day, the time but nothing change. Can somebody help me with this issue ?

Thank you.
Best regards.

Hello - please post a file that shows the problem - exactly as you have it, but you can place a box instead of your building to simplify matters. What is the current renderer?

Thank you for your reply Pascal.

My current render is Rhino but it’s the same if I turn on Vray.

Hello - Sun seems to work here:

Can you try disabling VRay completely in Options > PLug-ins page and then close and restart Rhino?
Any different?

I tried. Nothing changed.

Actually, shadows work but the thing is that shadows don’t move whan I use manual control…

Thank you for your time Pascal.

So, may someone help me, please ?

Hello -

please run the SystemInfo command in Rhino and post (copy/paste) the results here.

Also, which display mode are you using and, if that’s a factory-default mode, have you modified it from its defaults?
