It has a scope material now, just the circle with black around it idea.
I don't want to make the lines part of the material because it's scaled to fit the screen, and lines would become ugly at high resolutions (and possibly invisible on low resolutions). Still, the lines are all black now except for a single red pixel at the centre (which is there to help aiming at dark areas).
Something that looks like an actual scope would be awesome.
Also is there any way to make it so it doesn't move a certain number of pixels in jumps? It makes some headshots impossible to hit.
That's your mouse settings.
