Physics and Particles
Particle system can be atached to any mesh object. Control methods include weight painting, textures, curve guides, wind and vortex effects. Particles can be deflected by moving geometry
Hair strands can be created by a static particle system, supporting all particle control methods
Fluid simulator with fully animated inflow, outflow, obstacle and fluid objects. Gravity and viscosity settings can also be animated. Supports vector blur and is integrated with the particle system
Realtime soft body solver integrated in mesh, lattice, curve and text objects. Supports collision detection and particle field effects like Wind or Vortex, soft bodys can also be baked for faster playback/rendering
Game engine rigid body physics can be easily baked into animation curves
Realtime 3D/Game Creation
Graphical logic editor for defining interactive behavior without programming
Collision detection and dynamics simulation now support Bullet Physics Library. Bullet is an open source collision detection and rigid body dynamics library developed for Play Station 3
Shape types: Convex polyhedron, box, sphere, cone, cylinder, capsule, compound, and static triangle mesh with auto deactivation mode
Discrete collision detection for RigidBody simulation

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
Rendering
Very fast inbuilt raytracer
Oversampling, motion blur, post-production effects, fields, non-square pixels

Shading
Diffuse shaders such as Lambert, Minnaert, Toon, Oren-Nayar, Lambert
Specular shaders such as WardIso, Toon, Blinn, Phong, CookTorr
Node editor for creating and mixing complex materials
PyNodes: write your own Python shaders with realtime feedback, no need to compile
Material previews rendered by main render engine
Fast, realistic subsurface scattering
Blurry reflections and refractions
Tangent shading to give any shader an anisotropic effect
Versatile procedural textures system
Reflection maps
Normal, displacement and bump maps

Imaging and Compositing
Compositor tightly integrated and aligned with the rendering pipeline
MultiLayer OpenEXR files allow to store and reuse raw renderlayer and passes data
Complete list of composite node filters, convertors, color and vector operators and mixers including Chroma Key, Blur, RGB Curves, Z Combine, Color Ramp, Gamma Correct
Preview panel to define the portion of interest. A composite then only happens on this part
