Parameters

Name	Description
clearDepth	Should the depth buffer be cleared?
clearColor	Should the color buffer be cleared?
backgroundColor	The color to clear with, used only if clearColor is true.

This clears the screen or the active RenderTexture you are drawing into. In most other situations, some camera is drawing something somewhere, and probably is clearing already with the background color of the skybox.
