I'm getting black artifacts in my renders. It looks like black pepper.

I've already re-calculated the normals (they were already facing in the right direction, anyway). You can see the artifacts on the door and the awning:

Black artifacts in rendering

I'm using v2.68, but I get the same thing in v2.70.


The black artifacts are caused by intersecting meshes. In order to fix the issue, select the house model, enter edit mode and use W > "Remove doubles". Finally, go back to object mode and check if you have any duplicates of the objects in your scene, and delete them.

  • $\begingroup$ Thanks for your help. What you suggested fixed the problem on the awning, but I'm still getting the artifacts on the post and front door. $\endgroup$ – Mesh Head Jun 17 '14 at 11:51
  • $\begingroup$ I fixed it! Turns out, I had double objects in my post and on the door. Thanks again, user2926289! $\endgroup$ – Mesh Head Jun 17 '14 at 12:50
