SUbD now uses industry standard OpenSubdiv to compute subdivisions.
OpenSubdiv was developed by Pixar and released as open source in order to encourage fast consistent subdivision across applications.
A new SUbD Entity Info dialog is available exposing the new OpenSubdiv options.
Better control over your mesh smoothing.
Fine tune the UV mapping.
SUbD will use and preserve your WrapR UV seams.
Meshes can now contain internal faces.
Quad triangulation is now preserved for planar quads.
You can now adjust subdivision of multiple selected instances.
Crease Tool's performance is greatly improved.
Since OpenSubdiv now computes the subdivisions there might be minor differences in the result between version 1 and version 2:
This is probably the most noticeable change. In version 2 you will get different results if your mesh have faces not oriented consistently.
Some small differences with creases might be observed. OpenSubdiv creates much smoother (and correct) creases when you adjust the values up/down. In previous versions you might sometimes see the creases make small jumps.
Purchase one license for $40 using PayPal.
A license allows one person to use SUbD on any number of machines, but the license cannot be shared with anyone else.
Incremental updates (x.1, x.2 etc.) are free.
