Me and my friends are currently creating an android/iOS game using marmalade. We want to add an intro (animation) to it and we're wondering what's the best way to create and render an animation. Probably the easiest way would be for our graphics artist to create an animation in whatever software he likes and save it as *.avi or any film format. Then we would just display the film in game. But after a short research we came to a conclusion that it might be a bit (or very ) difficult using marmalade. So another idea was to create a 2D animation (as a series of layers and translate/rotate/scale/color&alpha change tranformations) in a 3D graphics software like Blender, save the animation (as keyframe information), then load it in our game and display. But we're not sure if that wouldn't be making a mountain out of a molehill.
So maybe there are easier ways (existing tools?) to create a simple 2D animation and rendering it in the mobile game (with marmalade)? Or, if the idea with Blender is ok, what 3D file format should we use? We need vertex position, texture and texture coords, colour and alpha information. Texture animation would be nice too.
