In their own words
akeytsu
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.
OPTPiX SpriteStudio
OPTPiX SpriteStudio creates 2D sprite animation data for projects ranging from short animations to game development. Its mesh and bone tools support deformation, and bone influence weights can be calculated automatically. Masking can define permeable overlap areas and effects such as wipes, with adjustable position, size, and shape. A designer can produce sprite animation data alone using the tool. SpriteStudio supports readable XML and compact binary formats, as well as instance and particle effect creation. Listed engine support includes Unity, Unreal Engine 4, and Cocos2d-x; game engine players and an SDK are available free of charge. Export options include PNG, GIF, WebP, AVI, MP4, SSCE, SSAE, Cocos2d-x PLIST, and Corona SDK LUA. It runs on Windows and macOS and requires an always-on internet connection, along with listed hardware and graphics requirements. The free Starter License is limited to companies with prior-year sales under JPY 10 million and has feature restrictions and attribution requirements. The Professional License costs ¥93,500 a year. A one-month trial includes SpriteStudio Ver.7 features but not SpriteStudio 5.
