Photorealistic Rendering

Blender now features a powerful new unbiased rendering engine called Cycles that offers stunning ultra-realistic

rendering.

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
