Your creature 3D model deforms in Mixamo mainly due to incompatible rigging, poor topology, or mismatched bone weights. - Incompatible rigging: A pre-existing skeleton may conflict with Mixamo’s auto-rigger, causing unnatural bends. - Poor topology: Triangles, ngons, or uneven edges prevent smooth deformation when bones move. - Mismatched weights: Inaccurate weight painting makes bones pull vertices unevenly. To fix this, remove pre-rigs before uploading, use all-quad topology, and adjust weights in Mixamo’s editor if issues persist.
