Our tcRotationInterpolator is a maya node that interpolates an arbitrary number of rotations. The algorithm works in quaternion space to have better results compared to the standard euler interpolation.
If you are planning to use one of our tools in a studio, we would be grateful if you could let us know.
Available for Maya 2014, 2015, 2016 and 2017.

How to use
- Load the tcRotationInterpolator plugin.
- Use the following mel command to create a node: createNode tcRotationInteprolator
- Connect the rotation of the input object to the Input[x].inputRotation attribute.
- Connect the output attribute to the input rotation of your object.
The node needs a reference rotation in order to interpolate the othes, please choose between these modes:
- maxEigenValue: The node computes automatically the reference rotation by estimating the mean rotation in quaternion space (it solves a system and takes the max Eigen value).
- minEnergy: Same as the mazEigenValue but minimizes the energy of the system. It computes a more precise result but it’s more expensive to compute.
- referenceRotation: It uses the rotation plugged to the referenceRotation attribute on the node. It’s useful in case you have already a reference rotation, for example if you are interpolating some joints you can use the bind pose of one of them.
Reference Rotation/ Reference rotation order
Rotation used as reference when the interpolation mode is set to “referenceRotation”
Input rotation/input rotation order/weight
Rotation to blend to and the weight of this rotation used by the inteprolator
