You may already be aware of DAZ 3D, in fact few people who work with 3D modeling and texturing haven't heard of or tried their lines of tools, models and resources. Today, DAZ 3D have released a new update to their Hexagon 2 3D modeling and texturing package (which is, quite possibly, our second-favorite subdivision modeler).
Hexagon 2.5 now supports sculpted prims for Second Life, among its already impressive array of features, and without much of the fiddling about and constraints that you might have to contend with some of the other software for which plugins are available.
Additionally, Hexagon 2.5 supports far more model export options, and a bridge that allows DAZ Studio models to be pulled into Hexagon, tinkered with and then sent back to DAZ Studio. Yummy!
