We present R-DMesh: a unified video-guided 4D mesh generation framework that tackles the long-overlooked pose misalignment dilemma. Given a static mesh and a reference video with arbitrary initial poses, our method automatically rectifies the mesh to the video's starting state and generates high-fidelity, temporally consistent animations. Beyond video-driven animation, R-DMesh naturally supports a wide range of downstream applications, including pose retargeting, motion retargeting, and holistic 4D generation.
