We create 3D models in Maya2011 and create PNGs and import the bunch into Adobe Flash CS5 to create a sprite.
I read somewhere that sprite-sheets can save space over making the sprite in Flash. How big of a difference does it make? None of our art team has experience in creating sprite-sheets. Is it worth learning it and adopt that workflow? How difficult is it? How much of a difference in file-size can we achieve?
Keeping size constraints apart, I see a draw back using sprite-sheets: I wont be able to create multiple combinations of loop animations using the same set of images. I can even create multiple sprites within the same SWF with our current workflow.
