Need some help to find an advanced rigged human asset

Hey guys! Need your help. Forever ago I went across an advanced rig of a humanoid, that allowed to scale any limb of the character independently preserving animations for all other parts of the body in their original places. The tool's demo showed a character that has been scaled and stretched in random weird shapes, allowed to animate the length of the hands while preserving animations between the knees, hips, and shoulders. The knee could stretch far in front, for the hips to keep their level when the legs were stretched; fingers became long as brunches but kept their animation undestorted... And so on. I am not quite sure if it was a blender asset yet I hope it was (could be for Maya though). In any case, if anybody finds it familiar, please let me know. I only remember the asset (or the tool) was quite pricy. XD
