Cocosbuilder Smart Sprite Sheet Test Case
Use Cocosbuilder 3.0 alpha 2 to open /SmartSheet/TestSmartSheet/sm.ccbproj
Play the default timeline, you will see the perfect animation.
Then open the xcode project and run it, you will see some frames blur out.
I think the problem is the texture packing cross, the plist is not rendered correctly: The animation is good when I packed those same texture frames using Zwoptex. Tested on iOS 6.1.
Also test it in cocos2d-x, the result is the same.
