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.
