What it is

AccuRIG is a guided, standalone auto-rigging tool for turning 3D meshes into animated cartoon characters and digital human avatars. It handles varied scan poses and models with different sizes, styles and postures, including realistic anatomy, exaggerated proportions, atypical limbs, obstructed shoulders and fantasy creatures with hind legs. Skin weighting supports articulation around hair, knees, elbows, hands, accessories and clothing. The tool can separate close-set fingers and rig varied finger types. Joint masking removes unwanted joints for partial rigs on incomplete limbs or non-standard poses. Finished characters can be saved in FBX and USD formats, with export destinations including Unreal Engine, Unity, Blender, iClone, Omniverse, Maya, 3ds Max, MotionBuilder and Cinema 4D. AccuRIG runs on Windows 11, 10 or 8 with 64-bit support. The free ActorCore plan costs nothing and supports one mesh in an A/T pose. Multi-mesh characters may be imported but cannot be rigged separately in that version. Advanced features are available in Character Creator 4.1.
