Can't turn off visibility of skydome

[hayley_allana_mills]

After searching how to make the skydome invisible while still using the light from it, I found multiple examples of people turning the camera setting under attributes to 0. However, this isn't working for me. Am I missing something?

Edit: It turns out its because I have two of the same skybox, and I had only made one of them invisible. It won't let me delete either of them though. Any ideas why?

Just hide one. Or unload the reverence.
