What akeytsu is

akeytsu is a 3D character rigging, skinning, and keyframe animation tool for animators, available on Windows and macOS. Its Auto-Rig creates a biped skeleton, skin weights, and controls after the user places five hot points and chooses spine and finger joints. Animation tools include a circular Spinner for transforms and inverse kinematics, along with reverse-foot, RF, and blendshape controls. Rigging features include a hybrid IK-FK solver, space switching, and mirroring. Skin Bind uses two passes, including rigid zones and a delta-mush-powered algorithm, and the software also provides skin painting tools. Projects use the native .AKT format; akeytsu interoperates through FBX and imports BVH and OBJ files. Listed integrations include Unreal Engine 4, Unity, CryEngine, Godot, Maya, 3ds Max, Blender, LightWave, Cinema 4D, Notch, Marmoset, Autodesk VRED, and Sketchfab. The maker recommends baking animations for export because other software cannot interpret akeytsu's proprietary IK and RF rig controllers. The 30-day trial includes the full feature set, is non-commercial, and is limited to one trial period per user. A separate free personal license is listed as valid for one year and renewable.
