In the game, I've seen asset types for animations that are of SpriteStudio. I have searched the documentation and cannot find any information on what this is.
I looked at the template project that purportedly covers SpriteStudio, but I don't see anything that really explains how to use it. There are various entities of type "SpriteStudio" that reference assets called SpriteStudio Animations. These assets show their source to be files with a ".ssae" extension. I assume these entities, assets, and resources are purposed to create the 2D animations within the demo.
I don't see how to generate ".ssae" files, nor is there any editor that I could find for the SpriteStudio Animation assets.
Is SpriteStudio separate software? Is it a sub-editor of the Game Studio? How do I create ".ssae" files?
