What it 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 selects spine and finger joints. A circular Spinner handles transforms and IK, alongside a hybrid IK-FK solver, reverse-foot controls, space switching, blendshapes and mirroring. Skin Bind uses two passes, including rigid zones and a delta-mush-powered algorithm; skin painting tools are also included. Projects use the native.AKT format, and the software interoperates through FBX while importing BVH and OBJ files. Integrations include game engines and 3D packages such as Unreal Engine 4, Unity, Godot, Maya and Blender. The maker recommends baking animation before export because other software cannot interpret its proprietary IK and RF controllers. A full-featured free trial lasts 30 days and is limited to one trial period per user; a free personal license is listed as renewable annually.
