MESH type image does not display

I am using Cocos Creator 1.5.1

When I change the sprite type to MESH in the editor the image I set for the sprite disappears.

Any idea why this is happening?
What is the use of mesh type images?

Can it be used to deform the image ?

there are 2 reasons mostly for using mesh

  1. for physics or 2. for Animation to get better controls like in dragonbones/spine you have to convert image into mesh object if u want to define some points (polygon) and animate them. I guess in cocos creator mesh is still in development mode.

Hello, any upate on this? Is it possible to use mesh sprites in latest cocos? Any ETA?
