    Toggle Post Process Material

    I'm trying to work up an anaglyph 3D post process effect--which looks fine, but I can't figure out how to make it so I can turn the effect on and off.

    It's really simple, I'm using two cameras and the colors are changed in a post process material--everything looks great, but I want to be able to use a UIScene button in Kismet to turn the effect on and off.

    It's easy enough to setup the script to turn stuff on and off but for this it's complicated--essentially either I need to set the material black (so it doesn't render) or I need to change the Post Process Chain to one without that PPMaterial. I've tried using a MaterialInstanceConstant with a Vector Parameter to change the material to black in Matinee, but it doesn't update to the PostProcessChain. And I don't know of any way to access the PostProcessChain in Kismet


    Any help?

      There's no point in it, UDK supports Nvidia 3D vision now
