SIGGRAPH 2026 training-free method for cross-morphology motion transfer (human-to-animal, animal-to-object) that avoids skeletons by operating on dense pixel-level motion flow, rewiring cached self-attention K/V features in a frozen WAN text-to-video diffusion transformer via retargeted positional encodings (TransPE).
