Draw a Dream, Make It Move
From creating short animations to developing games.
OPTPiX SpriteStudio, the animation creation tool

OPTPiX SpriteStudio substantially improves production efficiency by reducing complex work when producing sprite animation data. By using OPTPiX SpriteStudio, production of sprite animation data can be completed by the designer alone.

In addition, the produced data can be used as desired as the data is "extremely versatile" data that can be used in various game scenes. Supported in Windows and Mac OS and is equipped with an English mode.

Main Features

Mesh and Bone Feature

The traditional method to create a hair fluttering effect was to "utilize detailed settings for vertex deformation of each part," but now we can enable a richer, more life-like expression by using the mesh and bone feature.

This feature can be used with traditional animation creation methods, and more animations can be created more efficiently by using whichever method is most appropriate for moving a part.

Also, a major feature is processing the range of influence (weight) of a bone by automatic calculations with simple settings.

Mask Feature

Supports a "mask feature" to make a section where parts overlap each other permeable.

Effects such as the "wipe" seen on television programming can be easily achieved. Since the masked section is also handled as a part, the position, size, and shape can be changed.

Mask Feature Sample

"Extremely versatile data" supported by various game engines such as Unity and Unreal Engine 4

Players for game engines used all over the world in smart phones and game consoles are available for free. Supports a wide variety of data formats such as Unity, Unreal Engine 4, and Cocos2d-x.

The SDK is also available free of charge.

Other Features

High Utility: High readability XML format and compact binary format

Create animations quickly with the instance feature

Create particle animations easily with the effect creation feature
