Artifacts can show up as unintentional blotches, bands or cross-hatches on surfaces. Textures can flicker or crawl on surfaces from frame to frame during animations.
Especially in large scenes that have objects close together, background surfaces may appear to show through nearby surfaces. This is a result of how the camera’s clipping planes determine the depth position of geometry; the problem results from the limited precision used to store depth information. It is mainly influenced by the following camera parameters: near clip distance, far clip distance, and camera angle.
