The built-in Cycles rendering engine offers: GPU & CPU rendering Realtime viewport preview HDR lighting support Permissive License for linking with external software Fast Modelling Blender's comprehensive array of modeling tools make creating, transforming and editing your models a breeze. Blender's modeling tools include: Keyboard shortcuts for a fast workflow N-Gon support Edge slide, collapse and dissolve Grid and Bridge fill Python scripting for custom tools and addons Realistic Materials With Blender's new rendering engine the possibilities for materials are endless. Key features are: Complete Node Support for full customization Physically accurate shaders like glass, translucency and SSS Open Shading Language (OSL) support for coding unique shaders Fast Rigging Transforming a model into a poseable character has never been easier! Blender offers an impressive set of rigging tools including: Envelope, skeleton and automatic skinning Easy weight painting Mirror functionality Bone layers and colored groups for organization B-spline interpolated bones Animation toolset Whether it's simple keyframing or complex walk-cycles, Blender allows artists to turn their still characters into impressive animations. Blender's animation feature set offers: Automated walk-cycles along paths Character animation pose editor Non Linear Animation (NLA) for independent movements IK forward/inverse kinematics for fast poses Sound synchronization Sculpting Experience the joy of sculpting organic subjects using the built-in sculpting feature set of Blender. Sculpting in Blender includes: 20 different brush types Multi-res sculpting support Dynamic Topology sculpting Mirrored sculpting Fast UV Unwrapping Easily unwrap your mesh right inside Blender, and use image textures or paint your own directly onto the model. Blender allows for: Fast Cube, Cylinder, Sphere and Camera projections Conformal and Angle Based unwrapping (with edge seams and vertex pinning) Painting directly onto the mesh Multiple UV layers UV layout image exporting Full Compositor Blender comes with a fully fledged compositor built right in. That means no more exporting to third party programs, you can do it all without leaving the program. The compositor comes with: Impressive library of nodes for creating camera fx, color grading, vignettes and much more Render-layer support Full compositing with images and video files Ability to render to multiLayer OpenEXR files Multi-threaded Amazing Simulations Whether you need a crumbling building, rain, fire, smoke, fluid, cloth or full on destruction, Blender delivers great looking results. Blender's simulation tools include Fluid -- Realistic water and fluid simulations. Smoke -- Billowing smoke with flames and scene interaction. Hair -- Beautiful wafts of hair that blows in the wind and interacts with collisions. Cloth -- Amazingly realistic cloth simulations for clothing and environments Rigid Body Physics -- Makes any object destructable and collidable Particles -- For creating things like rain, sparks and shrapnel Game Creation Included in Blender is a complete game engine, allowing you to create a fully featured 3d game right inside Blender. The game engine includes: Ability to port your models to any third-party game engine Create or code your own game logic Full Bullet Physics integration Python scripting API for advanced control and AI Support for all OpenGLTM dynamic lighting, toon shading, animated materials as well as Normal and Parallax Mapping Playback of games inside Blender without compiling or preprocessing 3D spatial audio using OpenAL Blender 2.65 Blender 2.66 Blender 2.67 Blender 2.68 Blender 2.69 Blender 2.70 Blender 2.71
