Shaders on Objects creating "flaky black spots"
on Sep 23, 2014 at 1:03:40 pm

Hello. I've been trying to shade this for a while and at first everything was working smoothly until i got to the eye and the goggle rivets. In any assigned material it takes up those black...specks, and when i preview render the image, it messes up the coloring and textures of whatever I apply to it. I have tried deleting every material and going from scratch. I just now applied a lambert to the whole piece, but the same problem persists. Can't figure it out, really hope someone knows what's up.


and when i try to render it, it gets a bit "flaky" in parts.

Hi, looks very much like a near clip plane problem with your camera. Go into your camera attributes, set near to something like 0000.1 and the far clip to 1000000 see if that helps.

or try that the other way around, try to increase the near clip plane.

Thanks for the reply. I tried doing both..it did change it a little bit, but depending on how much you zoom in or out the black parts stayed. The render looks the same too.

hmm well it doesn't have any bl;ack spots in the render, I only see white splodges. Are you sure you haven't got any other geometry intersecting, it looks like geometry fighting for the same space, you haven't accidentally done a very small extrude? What happens to the scene if you add a standard sphere and the same shader?

Thanks, that seems to have solved the problem. I think when I extruded the iris, I managed to duplicate it as well.
