has anyone come across this yet? When i put a character into a scene and do a render and 2048x858 resolution, i noticed these weird black lines everywhere. But if i go into the character file and do a render they are gone. Wondering if its a camera normal issue or something.

I just added a basic diffuse material with no bump or normal map. So it seems its a camera issue i would think.

ok, i was able to recreate the problem, it seems to be some type of global positioning issue.

These artifacts do not show up when the character and camera are close to the origin of the scene, the further out I pull the character away they begin to show up.

Check your scale. The objects in your scene should have the real-world size.

It should also be nearly the world center.
This means not anywhere at 1000000km...

my unit scale im working in is centimeters.

Is this just a limitation at the moment and I have to work around it.

Besides manually moving my characters and cameras back to the origin is there anything else I could do?

If you can't move the mesh to the origin, you can render it as a separate instance or proxy. The mesh itself should have its origin nearby.

Have you tried adjusting the rayepsilon?

In some cases the characters in my scenes are far off in the environment.

In this case the character is quite far from the origin of the scene, which is where the character mesh origin is from the bind pose. So both scene and mesh origin is 0,0,0.

The entire character is being rendered as moveable proxy.

I have tried adjusting the rayepsilon, but it has no effect on these artifacts.

I can create a mel script that can transfer the animation on the god controls of the camera and character, that transfer them back to the origin for rendering. I was just hoping there was something else that could be done.
