Pharan Can you give us more information? What game engine/framework are you using? What Spine runtime are you using?
micenote sorry. i want using THREE.js run this files. but it can't run, you can tell me what the reason is?
Mario I'm sorry, I need more information than that. When you open the Chrome/Firefox/Safari development console, what does it say?
Erika When that happens to me, I usually tiped altas instead of atlas, or I mistyped the name of the animation or of the skeleton. Is it the case with you? Do you have a multipage atlas maybe?
