Yesterday Eyeon Software released the latest version of Fusion. Version 6 now supports an embedded stereoscopic workflow that is a bit different from Nuke and other systems. I have not tried it out yet, but once I get my brain around the new methods you can bet there will be a tutorial DVD looming on the horizon. Fusion 6 offers all sorts of new shader trees, a completely new 3D system, new blend modes, environmental tools, improved FBX, and much more.
