It doesn't just export sequential images of full frames, it can also export the actual animation data in XML format, so game engines can recreate all the animations using just the original source images (like body parts) thereby saving massive amounts of VRAM and disk space. It will also support tons of game specific features, like visually placing unlimited collision rectangles per frame (with names and numeric values for each!), unlimited action points per frame, unlimited named variables can be changed per frame, and sound effects can be triggered per frame. It also supports an awesome feature called “Character Maps” which lets you show, hide, or replace images from specific folders on the fly to make game features like customizable character appearance and changes in weapons, armor, etc super easy and efficient.
