Also note that setting this parameter will override this parameter for ALL materials in the scene. You can alternatively change this parameter on a single material using Material.setBoolean(String, boolean) This also will automatically adjust the faceCullMode and the PolyOffset of the pre shadow pass. You can modify them by using getPreShadowForcedRenderState()
    
    Parameters:
