If you are on Subscription (info here), you can now grab the Extension release for Autodesk Mudbox 2014. There have been a number of improvements to retopology and working with existing meshes.
Check out the video here:
The Extension for Autodesk® Mudbox® 2014 software offers new support for real-world production workflows, helping streamline the mesh refinement process and increase productivity. You can now create topologically symmetrical meshes while retopologizing, or from an existing mesh—a requirement for many downstream tasks. In addition, a new Caliper tool helps you accurately measure the distance between two points in linear space, or along a curve, making it easier to match a required scale.
New Symmetry Options for Retopology and for Existing Meshes
It’s now possible to enforce topologically symmetrical results when retopologizing meshes. Symmetry can be based on the source topology—enabling meshes to retain both topological symmetry and spatial asymmetry (for example, a face with a lop-sided grin)—or on a local or world axis, for completely symmetrical results; you can choose whether to copy painting and sculpting detail from one or both sides of the source. Existing meshes can also be quickly made symmetrical across one or more axes without retopologizing, with a new Make Symmetrical tool—this is particularly useful for models scanned from real-world objects, which often appear symmetrical but are not. Topologically symmetrical meshes are essential for sculpting and painting with tangent symmetry, and for many other processes throughout the production pipeline.
New Caliper Tool
A new Caliper tool enables you to measure the distance between two points on a model or along a curve. This is useful for helping to ensure that meshes match a desired real-world scale or fit with other objects or environments that may be created separately.
Extension available as of September 19th.
