Now all deforming objects can have their bounds dynamically updated, list of uses
-characters dynamically updating their physics bounds
-armature deforming mechanical objects
-dynamically updated bounds when a mesh is replaced
-tentacled creatures where each tentacle can collide with objects independently because of the dynamic updating of bounds
He mentions this is a frequent requent from these forums and now you have it, enjoy.
BTW: Don’t forget Benoit’s latest work for the BGE as well (the IK algorithm)
