Hello, i've tried to render MIchael 4 model and i got this black crease lines around his Eyebrow. ( image1)

Then i found that the eyebrow is made of a separate piece of geometry that lies ON the actual geometry of the face (image 2)

And i thought that problem is in the mesh, not in my videocard (By the way i am using GTX660M), or Octane poser plugin.

Next step - I decided to remove the vision for eyebrow in Poser (image3)

The final render. Without this black lines. (image4)

Maybe i am not right, if so - tell me please. Maybe there are some other ways to fix the problem.

Best, Alex.

You are right! Another way to solve it (other than inside poser) is to set the eyebrow opacity to 0 in the plugin.

Or set 'rayepsilon' under 'Settings/kernel' to 0.000001
This will also fix forehead "black lines" as well as any other geometry too close to each other.
