OPTPiX SpriteStudio
CRI Middleware lists its head office at 11/F, Infoss Tower, 20-1 Sakuragaoka-cho, Shibuya-ku, Tokyo, Japan.
What it is
OPTPiX SpriteStudio is a 2D animation tool for creating sprite animation data, from short animations through game development. Its workflow lets a designer produce animation data alone. Mesh and bone tools support deformation, and bone influence weights can be calculated automatically. Masking lets users define permeable overlap areas and effects such as wipes, with controls for position, size, and shape. The tool supports readable XML and compact binary data, along with instance and particle effects. It integrates with 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. A free Starter License has some restricted features and attribution requirements. The Professional License is 93,500 JPY per year, and a one-month trial covers SpriteStudio Ver.7 features but not SpriteStudio 5.
