552 Holographic Sight *actually works like a holographic sight* (Cycles)

Description:

(Original holographic model taken by darkmil's Benelli M4)

I have modified the model a bit visually and converted it to cycles. I have also created a reticle and adjusted it to only apear when being refracted through glass, though it may also unwantingly appear when the reticle has moved behind a glass window (I'll explain later) and appear and just have a floating reticle. But anyways I have moved the reticle far enough from the lens that it will apear that the reticle is staying on-target even as your camera angle moves side to side.

The reticle will apear out of nowhere if you move it close enough to something with a glass material, as the reticle will go behind it and refract it's light and show up, creating an unwanted floating crosshair.

I've made a YouTube video if anyone wants to see it in detail before you download it: https://www.youtube.com/watch?v=7o2Cn9mvFVQ
