Blender 2.63a [woodyman99]

Blender is free no code or crack needed

Transforming any model into a posable character has never been easier, with highly sophisticated methods of deformation calculation that allow realistic mesh displacement.
Specialized add-ons give you the power to create professional grade rigs for your characters in just a few steps.
Fast skeleton creation mode
Interactive 3D paint for vertex weighting
Fast envelope based skinning
Automatic Skinning that really works (heat equilibrium based)
Mirror editing (bone creation and weight painting)
Double Quaternion deformation reduces shrinking and other bone deformation errors
Volume deformer uses a mesh cage to deform complex meshes with great results
Bone layers and colored groups for better rig organization
B-spline interpolated bones; forget about elbow twists
Constraint stack for IK solver setup and other constraints
PyConstraints; if you need something not yet implemented code it in python with real time feed back, no compiling needed.

Using any of the multiple available tools to project meshes, it is straightforward to manage texture space for a given geometry.
Projections can be exported as image layouts, the unwrapped area can be adapted to existing images, apply multiple textures and special materials like specular and bump maps, alterations can be done interactively and see the results in real time.
Conformal and Angle Based unwrapping methods
Interactive transform of UV maps by vertex pinning
Proportional falloff editing of UV maps for smooth transformations
Seam based unwrapping
Cube, Cylinder, Sphere, View projections
Catmull-Clark subdivition of UVs for less distortion
Minimize stretch tool allows to reduce area distortio
