Villeurbanne, France
What it is
akeytsu is a 3D character rigging, skinning, and keyframe animation tool designed for animators, available for Windows and macOS. Its Auto-Rig creates a biped skeleton, skin weights, and controls after the user places five hot points and selects spine and finger joints. Animation tools include a circular Spinner for transforms and IK, plus 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 skin painting tools are provided. Projects use the native .AKT format; the tool interoperates through FBX and imports BVH and OBJ files. Listed integrations include game engines, 3D packages, and Sketchfab. The maker recommends baking animations before export because external software cannot interpret akeytsu’s proprietary IK and RF rig controllers. The 30-day trial includes the full feature set, is for non-commercial use, and is limited to one trial period per user. A separate free personal license is listed as renewable annually. Licenses are floating, with concurrent use limited to the number purchased.
