Thanks a lot, I don't understand why It doesn't work in my case...I show you below

the animation in question: https://ibb.co/7XsYzK7

Hello, i'd like to reproduce that effect, I started with a random effector with shader field but at the end of the animation I just want to reveal a logo. At that point, I blocked, can someone helps me please? I join you the final animation I need to reproduce and my C4D project.

thanks for your answer, i´m not sure to understand.
I tried with these settings, see below
Why with a aera light, i can't get the same effect on the shadow?

At the left of the image, i have the same window like the right and another daylight
The effect is like a miroir effect..

Hi, i'd like to simulate 2 suns illuminationg trought the tow windows.
But when i put the second daylight, it desactives the first one.
How can i simulate that?
Thanks
