AccuRIG

Overview

AccuRIG by Reallusion is a free, actively developed character auto-rigging tool that surpasses Mixamo in several key areas: natural language animation search, multi-character group motion, DCC-specific exports (Blender, Unreal, Unity presets), and FBX/USD format support. Game developers upload a 3D model, AccuRIG generates a production-ready rig, then optionally apply ActorCore animation packs. Unlike Mixamo, AccuRIG receives frequent updates and has a clear development roadmap — making it the safer long-term choice for studios building automated rigging pipelines.
