is it possible to override a lens shader? i cant seem to find the shader in explorer view to turn it off in a pass..

no, because it's a camera shader and cameras can't be included into partitions.
but there's a trick for that.
-connect a mix2 colors to the lens shader input.
-connect 2 lensshaders to the 2 different inputs (one can be a lens effects with nothing active if you want the plain camera)
-create a dummy object in the scene with a custom parameters set
-make that set drive the weight of the mixer
now you can override in partitions the parameters on the CPsets.

>make that set drive the weight of the mixer
this thread caught my interest so i tried to work through your method. i did everything but got stuck here. i tried to drag the custom slider into the mix 2 color weight but it won't take, also tried a link with.

in the explorer expand the color parameter and you'll find 3 divots for RGB, link the same parameter to all 3 if you want straight out balance or link them separately if you want color independant mixing.
