Sun in Rhino 7.13 doesn´t work, if I enable Sun- nothing happens!

I am using Rhino 7.13 on my macbook macOS Monterey 12.1

I see the shadow caused by the sun. To me it looks like it is working as it is supposed to. Try changing time and date (scroll the panel down so you get the calendar and earth map).

unfortunately its doesnt change at all- it stays the same when i disable or move the time lapse - and the shadow moves within the model when i turn it- so i guess its not the sun

thats a picture with the sun disabled

If you don’t have any lights, no sun nor skylight then you’ll be seeing the default scene light, which is a light from over the “left-shoulder” of the camera.
