What OPTPiX SpriteStudio is
OPTPiX SpriteStudio is a desktop tool for creating 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 lets users adjust the position, size, and shape of permeable overlap areas for effects such as wipes. The maker describes a workflow in which one designer can produce sprite animation data. SpriteStudio supports readable XML and compact binary data, plus instance and particle effect creation. Listed integrations include 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 restrictions and attribution requirements. The Professional License costs 93,500 JPY per year; the Business License starts at 400,000 JPY before tax. A free trial offers SpriteStudio Ver.7 features for one month, but not SpriteStudio 5.
