Camera Culling Mask help!

I am using three different cameras for my first person controller.

Main Camera: Culls Weapon Layer and UnderWater Layer, depth 0

Weapon Camera: Cull all except Weapon Layer, depth 1

UnderWater Camera: Cull all except UnderWater Layer, depth 2

-I have tried every combination of settings I can and the Underwater layer makes the Weapons layer disappear entirely.

-The only object with the UnderWater tag is this plane with an underwater effect shader on it that fills the camera's view. This plane's mesh renderer is off by default and set to on when entering under water.

-Before the plan'es renderer is set to on the UnderWater Camera does not effect the visibility of the Weapon Layer.

-As soon as it turns on the Underwater effect looks nice and the Main Camera renders everything fine, but the Weapon Camera doesn't render anything.

-Even after leaving water and the plane has the renderer turned off, the Weapon layer still wont show the weapons or anything.

-I set the Weapon layer to depth 4 to test, it showed the weapon and everything else black, some water shader effect was on the gun.

-I turned off the Weapon Camera and nothing from any camera rendered, all was black.

-I set the weapon Camera to cull all layers and the two other camera rendered fine. So if the Weapon camera doesn't render anything, than the rest works fine, but if i turn it off, everything is black??? WTH?

Is Unity just buggy and messed up or am I doing something wrong? Could it be the fault of this shader I'm using? All the problems seems associated with when the under water shader turns on.

 

Bumped for great justice!

Here is the Code for the under water shader I'm using:

Please

 

Please, this is a project killing issue.

 

Anybody.

 

Should I put the shader in a script on the camera instead of putting it on a plane as a child object of the camera?

 

Maybe someone would be more likely to assist if this was in the ShaderLab section of the forum?

 

Yeah, I didn't realize it was a shader problem at first. Maybe if a mod happens along they can move my post there, otherwise I'll start a new one later on.
