		@param reducedTexID					the id of the texture unit state the resulting cubemap should be bound to
		@param useDistCalc					flag to skip cube face update if object is far away
		@param useFaceAngleCalc				flag to skip cube face update if face is neglible
		@param distTolerance				distance tolerance used in face skip
		@param angleTolerance				angle tolerance used in face skip
		@param updateAllFace				defines if all cubemap faces should be updated in a frame or only one face per frame
		@param pass							the pass to operate on			
		@param parentRenderable				the object to operate on
		@param parentTechniqueGroup			the TechniqueGroup this RenderedTechnique is attached to
