 Unfold Mapping
            
 The Unfold Mapping method of procedural mapping eliminates texture distortion, but can result in overlapping coordinate clusters.
            The Unfold Mapping dialog lets you control how faces are unfolded.

                     Sets the unfold method by specifying whether unfolding starts with the closest or farthest face angle, with respect to distance.
                        In almost all cases, Walk To Closest Face provides better results.

                      When on, the final layout is scaled down to 1.0 square unit to fit within the standard editor mapping area. When off, the
                        final size of the clusters uses object space and tends to be much larger than the editor mapping area. For best results, keep
                        this option enabled.
