Circular Viewport?

[Mr_Grey]

Hi, need some help, im stumped.

I am making a spyglass script for my game (Think Sid Meyers' Pirates), and I want to show whats ahead in a viewport that can move about the screen.

I have everything done, except the viewport that allows you to see ahead is a square. I was wondering if there is any way to script in a circular viewport.

Thanks in advance
