akeytsu vs Live2D Cubism

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.

Live2D Cubism Editor turns drawn illustrations into animated 2D models, with tools for shaping expressions through mesh deformation, physics, and lip sync. Live2D says its technology is used in mobile apps, console games, VTuber streaming, and animation. The editor runs on Windows and macOS, including Apple Silicon and Intel Mac versions, and exports PNG, JPEG, GIF, MP4, WebM, MOV, MOC3, model3.json, and motion3.json files. Editor files are supported by nizima LIVE and other third-party applications; Live2D also provides an After Effects plug-in and Photoshop scripts. The PRO trial lasts 42 days, after which the Editor continues as the FREE version. FREE is limited to one 2048 px texture file, 100 ArtMesh, 30 motion parameters, 50 deformers, and 30 parts; exceeding those limits prevents saving. FREE commercial use is restricted to General Users and Small-Scale Enterprises with annual sales under 10 million yen. Cubism PRO for indie is listed at $13.26 a month.
