Rubik’s Cube Rig
Animation-Ready Rubik's Cube
This Rubik's Cube rig was designed with animators in mind. Layer turns are animated using standard Euler animation curves, allowing motion to be shaped with familiar Graph Editor workflows, ease-in and ease-out tangents, and fully editable keyframes.
A custom Maya dependency node manages the cube's internal state while evaluating live control input, allowing the rig to accurately reproduce the behavior of a dynamic hierarchy.
The result is a physically accurate Rubik's Cube rig that integrates naturally into Maya's animation pipeline while remaining practical for production use.
The rig and necessary plugin can be downloaded here.
Download the zip file titled “download this one”. Extract the files, then drag and drop the install.py file into the maya view port. This will install and load the plugin, build a shelf and button for the Save/Load tool, and add a 3×3×3 Rubik’s Cube rig to your Maya projects folder.
The entire C++ project can be found in the Rubiks Node folder if you want to poke around to see how it works.
Features
Animation
Animation-ready — Animate with standard Maya controls and editable Euler animation curves.
No baking required — Animation remains fully editable throughout production.
Physical behavior — Only one control family (Row, Column, or Slice) can drive the cube at a time.
Arbitrary cube sizes — Supports NxNxN sized Rubik’s Cubes
State Management
Save/Load permutations — Store and restore cube states at any point in an animation.
Timeline-friendly workflow — Sequential playback and frame-by-frame scrubbing work naturally, while the Save/Load tool handles non-sequential timeline jumps.
Technical
Custom MPxNode implementation — Built as a native Maya dependency node in C++.
Offset Parent Matrix workflow — Drives cubelets directly through Offset Parent Matrices without dynamic parenting or constraints.
Automatic ownership reconstruction — Rebuilds cubelet membership and control ownership from the committed cube state.
Lightweight serialized data — Stores only the committed cube and control state while reconstructing transient caches as needed.
