Spec score 8.1 #7 of 27 in 3D Rigging Software

What it is

Mesh2Rig is a Blender add-on that bakes animated or deforming meshes into standard skeletal rigs. It supports Cell Fracture and rigid bodies, cloth, soft bodies, shape keys, and other complex mesh deformations. Automated bone generation uses KDTree proximity to place bones inside a mesh, while Simple Mode assigns one bone per object for rigid debris. For deforming meshes, the add-on sets up Surface Deform modifiers automatically, without manual weight painting. One-click baking converts mesh animation into skeletal animation Actions. Batch Processing can rig, bind, and bake objects in Blender collections sequence by sequence, and Smart Merging can combine generated rigs and meshes into a Master Rig and Mesh while preserving animation. In the single-object workflow, users can adjust bone count, proximity, length, and optional bone merging. Mesh2Rig is free and open source under GPL-3.0, supports Blender 4.2 LTS and newer, and runs on Linux, macOS, and Windows. The maker describes uses including game development optimization, baking simulations to bones, and managing destruction scenes.

Strong points and limits

Strong points

  • Supports cloth, soft bodies, shape keys, and rigid bodies.
  • Sets up Surface Deform modifiers automatically.
  • Bakes mesh animation into skeletal Actions.
  • Batch processing handles Blender collections.
  • Free and open source under GPL-3.0.

Limits

  • Rotation constraints may cause artifacts with high bone counts.
  • Supports Blender 4.2 LTS and newer.

Who it suits

Mesh2Rig suits Blender users who need to convert mesh simulations or other deformations into skeletal animation. The listed workflows also target game development optimization and complex destruction scenes.

Verdict

Mesh2Rig covers several mesh deformation sources and includes batch processing and rig merging for larger scenes. Keep the rotation-constraint guidance in mind for automated rigs with high bone counts, and remove original animation sources after finalizing a rig.
