I'm creating animations in photoshop, but there doesn't seem to be any straightforward way to get them into sprite sheets. My workflow is create the animations, create a new photoshop file and then move and place the animations frame by frame into that new photoshop file, which involves me trying to work out what's the largest rect they will be in. When I used to work in Flash (vector) it was all straightforward, just right click on an animation movieclip and then it into a sprite sheet! I thought about loading the animation, frame by frame into Flash, and then turning them into movieclip and then doing the sprite sheet option but there's got to be a better way? I've tried the photoshop plug in which exports to a sprite sheet, but it doesn't seem to work.
