Complex and rich 2D animations created with OPTPiX SpriteStudio can be easily reproduced with Unity.

NOTICE

There are significant differences between version 1.3 and version 1.2.x due to the optimization to get faster than 3x and add a new feature "Effect."
So if you update your project using version 1.2.x or earlier to the new version 1.3, you need to reimport all of your SpriteStudio assets and modify your scripts which refers to SS5Player APIs widely.
Please consider when to update for your project.
