It is optimized for all joints, from shoulder, elbow, and knee, to fingers.
Reallusion launched a free rigging tool AccuRIG, which allows you to automatically create skeletal rigs for humanoid 3D models.
The tool can be used with ActorCore – its 3D asset library for mocap animations – and other software, like Unreal Engine, Unity, Blender, iClone, Omniverse, Maya, 3ds Max, MotionBuilder, and Cinema 4D. The models rigged with AccuRIG can be exported to FBX, USD, and iAvatar formats.
The tool recognizes 3D scanned humans with varying palm facing directions and raised arm angles, so it can be used for all kinds of A-poses and with 3D scanned people. It automatically analyzes joints and corrects the axis to save time and effort.
You can also use the manual joint definition to customize models with different characteristics. AccuRIG is optimized for all joints, from shoulder, elbow, and knee, to fingers. The tool can even correct posture problems such as arm penetration or leg distance. It can also generate stylized performances for cartoonish figures.
