Hi guys. I wonder if someone has a good idea about preventing the very obvious center of polar-uv’s from appearing in the final result:

Here I add a radial gradient in combination with smoothstep but:
(a) this gives a center-area which is 1.0 and this means a gradient-map would not catch nice gradients to colorize the center. it would be only 1 constant color.
(b) the radial gradient is still noticable.

Does anyone has a better idea?
