I am using sprite packer to pack my sprites and reduce memory footprint for a mobile game but, there seems to be no way to actually use these sprites from the atlas at runtime. The usual way would be to do a Resources.Load(blah) as sprite; The Atlas isn't in the resources folder so that doesn't work. It therefore stands to reason that there must be another loading command to grab stuff from the library at runtime and return it as a sprite. If not then what is the sprite packer actually meant to be used for. Currently it would imply that you would need to still have the sprites you packed in your scene from the beginning, which defeats all purpose of having them packed somewhere. I can't find a single official Unity manual page saying how you load the sprites once packed. Just one telling you how to use the sprite packager and roughly what it does behind the scenes.
