Hey everyone,

I have a spaceship in my scene that will have lights and I don't mind compositing a glow effect in post, but if I were to render out the geometry of where the lights are located solely, then lights behind the object where the camera can actually see will be shown as well. How can I make sure that only the lights that will show are the ones the camera can see at a specific time?

The first picture shows the geometry with the blue colored lights and the second shows the lights by itself. Notice how you can see all the lights now since the rest of the geometry is disabled

at obj level set the geometry containg the spaceship under Render to Matte Shading.
hope it works.
