cheat? full screen dont really offer much of a bonus unless your snipe camping like a li'l bitch. if your constantly moving from spot to spot after killing one or two people you dont need widepan scope.
anyway cant be bothered to post screenies but i use animated scopes, groovy little inward pointing arrows at the target area.
basically partly thanks to you doing that animated avatar thing, i downloaded it and found out abou the AnimMap script. after some experimenting i just adapted it, made 4 seperate tga's with the arrow's moving in each frame. because the tgas are clamped you need to clamp them individually so your shader looks like this:
if you dont clamp the tga's when the game mirrors it all up the edges of the tga's don't meet properly and you get gaps between each tga, looks horrible. arg i suck at the animation thing anyway, there's a bit of flashing where i screwed up the some of the alpha's,
