Weird error in render

[OlaHaldor]

I have a very simple scene setup for our animation project at school. The scene consists of
- Ball (with animation cache from Maya)
- Box (with animation cache from Maya)
- Ground plane
- Two boxes and three pyramids in the background to make it easier to read the camera movement in this simplistic scene

I've been rendering a little bit now and I see an error in one of the pyramids in the background. I'm not sure why it's happening. All the geometry in the background are different objects, and have the exact same surface settings, a diffuse material. So they shouldn't reflect anything or be glossy.

Any ideas on how/where/what to look for?

Let me know if you need more info.

Perhaps the scene is too big, or too small. Try to change the ray epsilon value in the kernel that your are using from the default 0.0001 to 0.001 to see what happens. Also please check that you don't have a overlapped triangles on this object.

I'd say the scene is rather large. You can't even see the ball and box objects when I zoom out to see the entire scene. And they are each 1m in size.
The background is made huge and put so far in the background to get just enough of the parallax effect when moving the camera.

I set the Ray Epsilon to what you suggested, and this fixed the issue. Thank you!
