Digimation has announced that the upcoming (1.1) release of their Stitch cloth simulation plugin is scheduled for the 2nd week of October and will include many new features such as: real-time cloth simulation (the ability to interactively drag cloth objects in your scene), many new types of group constraints, cloth properties on a group by group basis, a new cloth to cloth collision engine and the ability to collapse stitch simulations to vertex animation and bake the animation into the mesh.
More information available at this month’s Digimation newsletter.
