Hi Community.
I have a 3D environment with lights following an object(tiff seq). The lights are purely position markers from a Cinema 4D .aec file which the composition's camera is also from.

So my question is: Can I get the real (2D)screen coordinates of the light (Light's coordinates on the camera's screen)from anywhere?

To attach a 2D null to a 3D light, add the following expression to the position value of the null:

thisComp.layer("Light 1").toComp([0, 0, 0]);

Assuming your light layer name is "Light 1"

Thanks Kalle, been waiting for that answer for days!

I thought there must be a simple expression for it, but I didn't know what I was looking for.

Thanks again.
