Hi Guys! Spine is a great tool, I really love it! I use it for cocos2d-iphone project.
I run into a problem with project exporting. I use JSON format with "Texture packer" option selected. My image files contain digits at the end of their names, like "left_hand_1", "left_hand_2" and so on... When I first exported the project and tried to run it on ipad I got the runtime error "Error: Region not found: left_hand_1". I looked at spineboy.atlas file and found that instead of "left_hand_1" and "left_hand_2" region params there were "left_hand" and "left_hand", seems like texture packer cuts of digits when exporting. Keeping this in mind I replaced digits with letters, "left_hand_a" and "left_hand_b" and this time everything worked brilliant.
So personally I found the workaround, but it would be great if you could check and fix this exporting issue.
Thanks.
