Motion2Motion is a no-training motion migration framework designed to address the challenges of animation migration between characters with different skeletal structures. Traditional animation retargeting techniques have strict requirements on the skeletal topology of the source and target characters, making it difficult to deal with characters that are very different (e.g., human vs. quadruped).
The tool addresses industry pain points through three major innovations: 1)Zero dependency on training data-- Only a small number of sample actions from the target character are required; 2)Sparse bone mapping--Minimum of only 6 key skeletal correspondences; 3)Real-time visualization--Integrated into professional workflows via the Blender plug-in. This groundbreaking approach enables developers to generate high-quality animations of a wide range of non-human characters with the same set of motion capture data, dramatically reducing production costs.
