Game Fog Issue

Hello.

I am having an issue where I apply the Global Fog effect to the left and right camera for the OVR in Unity and it often comes with some off offset, not aligning properly with the terrain or models. I have provided to pictures below:

Has anyone experienced this issue or know a possible fix?

    Yes, this is a known issue.

    As far as I know it has to do with the way we are altering the projection matrix to do the stereo.

    Unfortunately I don't know of a fix right now. I can try to bug one of our Unity developers to see if there has been any progress here. Otherwise you may have to write a custom shader for the fog.

    Yeah the fog shader would need to be rewritten for the Rift's offset projection matrix. Too bad I don't have all the time in the world..

    Thanks for letting me know, guys.

    If Dreadhalls has it working, I assume the edited the shader.
