Hello, I practically managed to develop my effects. But, I can’t get my planet earth to spin.

I just wish the earth would turn.

Hello,
when I connect to the page the clock does not turn. I have to click on the little clock at the bottom left.

I just wish the earth would turn quietly.

thank you in advance
