title: How to import 3d character with animation in mac application.
body: <p>I created a 3d model with some animations in maya. I want to use it my mac application. One way I know is to export as dae file and use this. But most of time my dae file is not being exported and i get warnings as "null not supported by collada". is there any other way to use these models in app or how can I fix this error while exporting .dae file. </p>
