ViewDirection UVs

Hey,

I have a problem that I feel many might come across with VR and having multi cameras.

I want to get screen space UV's but from the center point between both cameras so that it doesn't appear different to each cameras view angle.

I gave it ago with my limited maths skills and turned out I was wrong. I was passing in the camera up and right vector local from its transform to see if I could get it to work but to no avail.

I feel this might be useful to a few people in the near future.
