Closing for lack of explanation.

hmm I think I know what this person was trying to say, I remember when I was using shaders, when in some vehicles, the view would be a total blackout instead of being able to see. as much as shaders were awesome I stopped using them because if it. I think this was the same thing with the binoculars. If I have time il test it to see if its the same thing. But the vision bugs were happening at an early version of shaders. Another alternative is just not to use shaders.. lol
