[Problem] Black area on obj

[amineghorab]

Hi,

Anyone know why I have this black area in my sphere ?

It disappear when I move the object around but when I place the sphere on top of the surface, I have this black area appear.

FYI, I have the same problem in live viewer and render view.

Thanks for your help!

Hi amineghorab,
what is the scale of the sphere?
If it's too tiny, you can have this kind of issues, and you need to correct the Ray epsilon value in the Kernel settings.
