Auto Rigger is a mesh auto-rigging library that imports OBJ/FBX/glTF meshes, analyzes parts and symmetry, then builds a skeleton and skin weights using geometric pipelines or several neural models. It bundles loaders and pure C# inference for RigNet, UniRig, Puppeteer, MagicArticulate, RigAnything, plus export to FBX and vmdl. It also has optional cloud offload helpers for running these models on vast.ai instances via generated scripts and a small remote HTTP service.
An Editor Auto Rigger tool that lets a creator add an FBX, run analysis and rigging locally or via Vast.ai, preview and tweak joints, then export a skinned FBX and compiled vmdl into the project. It has editor windows and dialogs for model selection, joint editing, GPU rental/offload, and settings, plus unattended gate code to run rigs and write results for CI-like workflows. It downloads model checkpoints with resume and hash verify, stores per-project settings, and talks to Vast.ai with a user-supplied API key saved to a local JSON file.
