Lighting isn't consistent between camera angles

Lighting isn't consistent between camera angles

Hi
I've been lighting and texturing a scene and have been having trouble getting lighting consistency when I move around my cameras. Sometimes the scene is lit really well, and other times its as though the lights aren't even reading. I've been trying to trouble shoot this for two days and am at a loss. I'm attaching a link to the scene file. If any one could help me understand what is going on, that would be so great! I put images of the lighting differences in the folder as well. (no settings were changes between these images) just different camera positions.
Thanks!
Joel

I think that there's very little actual light in your scene at the moment. Some frames look brighter because of the visible light. Turn that off and it's almost 100% dark from every angle.

The problem seems to have something to do with the water planes on the floor. They're blocking the light from below, and perhaps also blocking bounce light (because you have generate GI turned off in the materials). Delete those materials and the scene brightens up considerably.

AH!!!! Thank you very much! I'd never have thought of that. Guess I'll fiddle around with the floor layers to get it working properly. Yay! so excited.

Just checking out some more things and it turns out that the culprit is the absorption distance of the Liquid - Water Ocean transparency. Change it from 25cm to 1000cm and the difference is night and day. Weird, considering that the material is on a flat plane. I guess the absorption distance just depends on the surface normals?
