Symmetrical Retopology can now be created in Mudbox. In addition, a new Caliper tool helps to accurately measure the distance between two points in linear space, or along a curve, which makes the job easier to match a required scale. The Retopology toolset updates and the new Caliper tool are part of the upcoming 2014 release of Mudbox.
