Blender 2.45 RC2

Blender is the open source software for 3D modeling, animation, rendering, post-production, interactive creation and playback. Available for all major operating systems under the GNU General Public License. Revolutionary non-overlapping and non-blocking UI delivers unsurpassed workflow ; Flexible and fully configurable window layout with as many screen setups as you prefer video sequence editing, character animation action editor, non-linear animation mixer, image/UV editing, file/image selection and file management ; Built-in text editor for annotations and editing Python scripts ; Consistent interface across all platforms .

Features:
>A range of 3D object types including polygon meshes, NURBS surfaces, bezier and B-spline curves, metaballs, vector fonts (TrueType, PostScript, OpenType)
>Character animation pose editor
>'Ipo' system integrates both motion curve and traditional key-frame editing
>Mirror modifier with middle vertices clipping and automatic deletion of inner faces
>Non destructive real time Boolean and Array modifiers
>Mesh modeling based on vertex, edge and/or face selection
>Smooth soft selection editing tools for organic modeling
>Python scripting access for custom tools
>Armature (skeleton) deformation with forward/inverse kinematics with pole target support
>Auto IK allows posing FK chains easily
>Non-linear animation editor for mixing individual actions created in Action editor
>Automated walkcycles along paths
>Very fast Catmull-Clark subdivision surfaces with optimal iso-lines display and sharpness editing
>Full multiresolution sculpting capabilities with 2D bitmap/3D procedural brushes (Paint, Smooth, Pinch, Inflate, Grab) supporting symmetry
>Modifier stack deformers such as Lattice, Curve, Armature or Displace
>Animated constraint system
>Vertex key framing for morphing, with controlling sliders
>Edit and create new blendshapes from existing targets
