Uneven lighting in cycles render I'm making a new animation and for some reason, the lighting in the render isn't even.
I've tried adding an area light but no matter how bright it is, the dark faces on the right don't show any change.
It's all indirect lighting and with the symmetry, I want both sides would be lit the same way.
Here's a frame that shows what I'm talking about. (Surrounding the coin-op on the right hand side, it's all dark) 
Any help is appreciated. I'm a bit stumped.
Edit: I've also noticed some splotches of darkness above the coin-op on the left. Could it be the texture?
Second edit: Link to file coming soon. Clamping and environment lighting did basically nothing.

Sorry it took so long to get my file uploaded! Hope this helps!
Difference in lightning does Material 2 - Magic texture.
This node generates black material on some faces differently, depence on object position.
On the left side are black back sides of object on the right sides are black front sides of objects.
Disabling node from node tree fix the lightning issue.

Node attached into Normal socket generates blacks on all negative XYZ axis directions.

I don't know what is a proper way, but ussally you should plug node into Color socket. So try this.

Plus as already mentioned - you have overlaping objects with different materials. But even I kept only one side and Mirrored with modifier, issue was there.
