Hi Dinesh,
I've been trying to improve my graphic importing workflow, and was wondering if there's any way to just have a @4x image and turn it into a @2x + @1x spritesheet automatically? Right now I export @4x graphics from Flash/Photoshop, find the files and run them through a downsizing program, import them to Unity, and wait ~30 seconds for a big spritesheet to rebuild. It would be great if I could find a way to cut out a step, or otherwise make going from Photoshop -> Unity as simple as possible. All the ~2 second, ~10 second, ~30 second workflow delays, really add up. Thanks!
