Blender is open-source software for 3D modeling, animation, rendering, post-production, interactive creation and playback.

New in version 2.64rc2

VFX Mask Editor: Masks can now be created in the image and movie clip editor. They can be used in compositing to define areas of influence for nodes, block out unwanted objects, or help with green screen keying among other things. A mask datablock was added, consistent of splines that can be drawn and edited with the usual tools. Feathering can be controlled per spline point. Animation of these masks is possible with standard keyframing and drivers, but also by following motion tracks and parenting to other masks. Motion Tracker: Motion tracking was significantly improved by adding planar tracking, and unifying the existing trackers into one Hybrid tracker with finer control. A dopesheet view for markers was added in addition to the curves view. Tripod solving is now supported, for the case where the camera only rotates without moving. Green Screen Keying: Two new compositing nodes have been developed which are aimed at making green screen keying easier. There is now a new keying node conveniently combing various features from existing nodes along with a new keying algorithm, to makes setup much faster. There is also a keying screen node which produces a gradiented plate to deal with uneven colors of green screens. Colors & Rendering Color Management: OpenColorIO is now integrated into Blender, along with a redesign of the color management system. Previously Blender only supported two color spaces, linear and sRGB, now many more are supported with finer control over which color transformations should be used for display, applied on renders, and used for loading and saving image files in different color spaces. Cycles Rendering: Cycles now includes a new non-progressive integrator with finer control over sampling, tiled rendering with support for save buffers, considerably faster BVH building and multithreaded image loading, and motion vector and UV render passes. New nodes are light falloff, object info, particle info and brick texture, and image texture nodes can now do blended box mapping and handle image sequences. There is also support for fisheye camera rendering, along with various other new options. Sequencer: Various speed improvements were implemented in the sequencer, mostly related to caching and multithreading for effect strips. These changes make color grading more interactive. Improved options for easily comparing the original reference and graded images were added. Modeling Mesh Tools: Bevel and inset now are modal operator with mouse control, a wire frame tool was added to turn edges into wireframe tubes, and vertex/edge/face sorting tools were improved. Sculpting: Sculpting has received some major improvements such has masking to control which areas of the mesh are influenced by sculpting, new brush map modes to control how textures are projected onto the model, and an input stroke averaging option to make brush strokes smoother. Skin Modifier: The Skin modifier takes a skeleton made up of vertices and edges as input and generates a polygon skin as output, consisting mostly of quads aligned along the edges. The output is mostly quads, although some triangles will appear around intersections. Other Game Engine: Lamps and shadows were improved with support for variance shadow maps, shadow color, sun lamp shadows and lamp textures. Non-power of two textures and compressed textures will now load faster and use less memory. A new Character physics type was added, designed for player controlled characters for which a full dynamics simulation would give unwanted behavior. Collada: The Collada exporter has been improved for better support of export to game engines, with more fine grained options to control which data is exported. Small Features: Apart from the major improvements in different areas, there were lots of smaller changes such as improvements in node editor, smoke, user interfaces; new tools for curves and meshes.
