CloudRig vs Mesh2Rig

CloudRig has no write-up on Specifiction yet; its figures are above.

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.
