Blender Portable 2.68 is the popular Blender open source software for 3D modelling, animation, rendering, post-production, interactive creation and playback packaged as a portable app, so you can do your rendering on the go. This release updates to the latest version of Blender. Note that settings will be reset on upgrade from versions prior to 2.57b. It's packaged in PortableApps.com Format so it can easily integrate with the PortableApps.com Suite. And it's open source and completely free.

Software for 3D modeling, rendering, animation, post-production, interactive creation and playback. Modeling. A range of 3D object types including polygon meshes, NURBS surfaces, bezier and B-spline curves, metaballs, vector fonts (TrueType, PostScript, OpenType). 'Smooth proxy' style catmull-clark subdivision surfaces. Boolean mesh functions. Editing functions such as extrude, bevel, cut, spin, screw, warp, subdivide, noise, smooth Soft selection editing tools for organic modeling. Python scripting access for custom tools

Blender 2.68 released - July 18, 2013
The Blender Foundation and online developer community is proud to present Blender 2.68.
Many different mesh modelling tools were added and improved. Cycles render performance was improved on Windows and on GPU's. The motion tracker can now automate placement and choice of markers more with new tools. Smoke rendering quality has been improved to reduce blockiness.
Python scripts and drivers are now disabled by default when loading files. This is for improved security, without this feature malicious .blend files could cause problems. See the Python security documentation for details.
- Modeling
Improved bridge tool to bridge multiple loops at once, subdivision, surface blending and bridging face regions. New grid-fill tool filling a grid from edge loops, X mirror and projected proportional editing, snap to symmetry, face split option for dissolve, vertex connect cut across faces.
- Physics
Smoke has improved rendering quality avoid blockiness, and subframe simulation support to handle fast moving emitters. Particles can now be emitted from faces generated by modifiers that were not in the original mesh.
- Usability
Improved weight painting tools, mask modifier for sequencer strips, 2D image paint more consistent with 3D painting, better key shortcuts display, quick enabling and disabling of multiple layers or visibility, auto indent for multi-line Python statements,
- Addons
New addons are Texture Atlas to bake shadow and lightmaps for an entire scene, and Edit Linked Library, for quick editing of linked assets.
- Cycles Render
Rendering performance has been improved on CPU and GPU and support for new GPUs was added. A new Mist render pass is available, Ray visibility is now supported for all light sources, and new Nodes have been added. Hair rendering on the GPU has been enabled as well.
- Motion Tracker
Some new features and smaller improvements to existing ones were done for motion tracking. Main features are markers' position refining, which allows you to refine marker position after it was occluded by an object, and automatic keyframe selection, which tries to automatically find a best keyframe for the reconstruction.
- Python Security
Auto-running Python scripts can now be controlled more securely.
- Bug fixes
In addition to the new features, over 280 bugs that existed in previous releases have been fixed.
