Cheetah3D 4.1 has been released today. The first minor update to Cheetah3D 4.0 fixes most of the problems reported after the release of v4.0. But it also adds some very powerful new features which didn't make it into v4.0. For example a 2D IK solver (or rotational plane solver) which is very convenient and predictable when animating arms and legs of characters. Furthermore v4.1 adds some more constraints tags which are also very helpful for animations purposes. New features in Cheetah3D 4.1:
added 2D IK solver
added point constraint tag
added orient constraint tag
added IK baking command to take manager
added support for pole vectors to IK solver
added prefered angles properties to IK solver
added support for stiffness to IK solver
camera uses full transformation hierarchy now
improved object drag & drop in object browser
improved vertex weight tool
fix FBX material export bug (caused by subdiv modifier)
fix FBX take export bug
fix FBX pre/post rotation import bug
fixed bug in symmetry creator object
batch .jas -> .fbx converter automatically bakes IK
