FBX import is now supported, along with improved export. New mesh modeling tools were added and existing ones improved. Cycles subsurface scattering and hair shading were improved, along with the addition of a new sky model, shading nodes and tone mapping in the viewport. The motion tracker now supports plane tracking, to track and replace flat objects in footage.
We have been testing this final release using three 'release candidates'. The official release is now available, published October 30th 2013.
The Motion tracker now supports plane tracking, which can be used to replace billboards, screens and other flat things in footage.
AddonsFBX Import support has been added and FBX/OBJ can now export split normals (without the need for the edge split modifier).
Sky rendering now uses a more accurate sky model. New blackbody, vector transform and HSV nodes were added. The non-progressive integrator was renamed to Branched Path Integrator, and is now available for GPU rendering.
Tone mapping now works in the viewport, with photographic film emulation.
More FeaturesLists in the user interface can now be resized, sorted and filtered. Further there are small improvements for vertex parenting, empty objects, the shrinkwrap modifier, mask editing, armatures, f-curves and drivers.
