Sculpting / Painting

Unwrapping UVs was improved by using a simpler unwrap method. Numerical input is supported for changing brush size, detail size and strength. The latter one can now also be changed for Grab and Snake Hook brushes. When painting with masks, the face-mask edges are hidden to give proper visual feedback of what you are painting on.

Similar to the Compositor, an option to show the current frame as a backdrop has been added. Strips can be snapped to others by pressing the G key while moving them and their content can be moved independently of the strip itself (S). A few minor things were also made, such as an option to toggle all waveforms on/off, or drawing of meta-strip range while editing them.

More Features

Several optimizations: mesh deform modifier now uses SSE2 with multi-threading, compositor’s gaussian blur node implemented in OpenCL, vertex parent optimized for a few cases. In 3D View added GLSL specular transparency support for Blender internal materials, and support for specular highlights in cycles materials. Motion Tracking predictive tracking has been implemented now, enabled by default and doing magic under the curtain. Added shortcuts for masks and tracks copy-paste operators.
