[SOLVED] Not sure what instance to set to an object.

I know the formating is potato, I couldn't figure out how to get it in here properly, sorry. I attached the script, just in case there was more info needed.

I'm getting an "NullReferenceException: object reference not set to an instance of an object" error on line 498. I don't have a targetCamera game object or camera, but I have tried the other cameras with no luck. For reference I am trying to implement volumetric clouds by having them on the layer Clouds and having a second camera only see those clouds so they don't appear in front of other objects on screen. everything is working as far as I can see crepuscular rays coming from the sun and moving with the clouds, but the clouds aren't rendering in, just those rays. I am fairly new at c# and Unity so I am probably derping over an easy fix and I probably left out information that you guys might need so let me know. Any ideas? Thanks
