What's Causing This Surface Pattern?

[jmilton]

Hi,

Does anyone know how to get rid of this surface pattern? Looks like a bullseye. It's on the surface before I add a texture to it.

Thanks,
Jeff

It`s the Rayepsilon value I think, try lowering or increasing it!

Thank you so much for the tip. Increasing the Rayepsilon did the trick in the Kernel.
