Depth buffer error?

[zbych]

I have torus in the center of scene, when camera look at it from one side it is rendered ok, but when I move camera to other side it looks like a depth buffer error. Any advice how to avoid this kind of problem, is any cure for this?

Check if transparency is enabled for that object and disable it.

Thanks !!  , it helped, but I didn't enabled transparency in this object.

The loader does this, if the file contains that information. Some files do even if the object should actually be opaque.
