Artifacting and banding when camera is really far away using ScreenSpaceRadius

[kitaedesigns]

Some artifacting appears when you zoom out on models, the banding seems to increase with Radius levels.
I've attached an image of the problem and my settings for AO.

You can fix this my adjusting the bias.

Can a static bias value fix this or does it need to update the bias value with the distance from the camera?

You can use the biasOffset and biasMultiplier parameters - they let you make the bias a linear function of the automatically computed bias. Then you can fiddle around till u find what works.
