Hi, I really appreciate the help and after much research I found it.
I used a template and it came with a set up I was not aware.. So the issue was the optical flares, this effect is the one that creates the flare on the lights, I was not aware of this.

thank you all for the help and sorry for any trouble.

if I turn off the light when is passing behind the object then I don’t have the luminosity that come from it ! I need to turn off the light spot emitter, not the luminosity !

Hi, I should have started with showing the picture…. in anycase, I tried turning off the eye (first icon for the layer) and that turn off the light as well !
really don’t know how to manage this ! strange how such a powerful tool like AE makes this simple needed feature so difficult to find !

Hi, thank you for helping, I will try to be more clear, maybe the picture helps.
When the light is passing behind a 3D object it should not be seen from the front.
The illumination of the scene is correct, is just the “light emitter” that is not hidden and that is not correct.

Hi, thank you for the reply but I am referring to the light source itself, I want it to be hidden when it passes behind and object.

Hi to all, I am trying to light a scene with a spot light but I don’t want to see the light source emitter, only the light cast, how can I do this !? Thank you in advance for the help.
