When you key opacity at 0, 1, then 0 - when you play the animation player in the editor, it does show the intended behavior. However, when you run the scene or play the game, it does not fades in (from 0 to 1) then fades out (from 1 to 0), instead it just pops in and out as if the code show() and hide() are being executed.\r\n\r\nI've attached a project showcasing this issue since it's difficult to show it through screenshot:\r\n[AnimationPlayer-Opacity.zip](https://github.com/godotengine/godot/files/84103/AnimationPlayer-Opacity.zip)\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/godotengine/godot/issues/comments/170354094","html_url":"https://github.com/godotengine/godot/issues/3301#issuecomment-170354094","issue_url":"https://api.github.com/repos/godotengine/godot/issues/3301","id":170354094,"user":{"login":"akien-mga","id":4701338,"avatar_url":"https://avatars.githubusercontent.com/u/4701338?v=3","gravatar_id":"","url":"https://api.github.com/users/akien-mga","html_url":"https://github.com/akien-mga","followers_url":"https://api.github.com/users/akien-mga/followers","following_url":"https://api.github.com/users/akien-mga/following{/other_user}","gists_url":"https://api.github.com/users/akien-mga/gists{/gist_id}","starred_url":"https://api.github.com/users/akien-mga/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/akien-mga/subscriptions","organizations_url":"https://api.github.com/users/akien-mga/orgs","repos_url":"https://api.github.com/users/akien-mga/repos","events_url":"https://api.github.com/users/akien-mga/events{/privacy}","received_events_url":"https://api.github.com/users/akien-mga/received_events","type":"User","site_admin":false},"created_at":"2016-01-10T14:41:51Z","updated_at":"2016-01-10T14:41:51Z","body":"Note that after doing these steps the animation should play fine in the editor.
