we have been using texture packer pro, so we already have atlases and text files as well as fonts from hiero...i found one post in the forums that explained how to create an atlas using externally generated files...however if i do that, and then follow something like the "basic usage" video...i do not get a drop down of the list of sprites in the atlas...instead a window pops up to pick the sprite...i also can not get the TP Import field to actually fill out with anything. Is there a better way to manually create an atlas?
