BoneRNG

BoneRNG is an add-on that randomizes the rotation, location, and scale of bones within an armature. Operating directly from the N-panel in Object Mode, the tool applies varied transformations to selected rigs to generate unexpected poses or break up predictable animation cycles.

It includes options to either add to existing transformations or replace them entirely, alongside controls for tuning the noise scale across different transform channels. The add-on can also automatically insert keyframes for the newly generated transforms to facilitate the creation of looping animations or particle effects.
