Using Gimp 2.8.4
I am developing an animation for a game in gimp. The game does not require a gif animation - I load individual images as frames, usually pngs, and animate them in the game engine. The animation frames depend highly on transparency, and when I preview the animation using Filters -> Animation -> Playback, everything looks completely wrong. I would be fine with simply exporting the animation to preview it, but I don't see any options. I tried installing the apng plugin, but that did work (get an error saving the images.) I tried exporting as an mng, but I am not able to find software to view it.
Does anyone know of a way to preview animations in gimp that allows transparency, and doesn't compress the frames? Or maybe a better animation format that Gimp can export to?
