During this quarantine time I am attempting to make a quick cartoon character! I wanted to use just some procedural gradients to create the eyes. I wanted to be able to link up sliders to sizes/colors to animate inside C4D/octane entirely.
I am having trouble with the aliasing of a circle while using the gradient option. Straight lines can appear somewhat crisp, and I can feather the edge SLIGHTLY and it takes down a bit of the aliasing, but I want a hard crisp edge as like the outside of the eye.
Any idea why this circle is so janky? Or, any better way to create this effect inside c4d/octane without using an image texture?


This is my current quick setup, but even just a black and white gradient as the input will appear busted up.
Thanks for the help!
