I created a simple sample COLLADA document.
It is called Dice.dae, an extension to the cube.dae with texture.

It has one set of texcoords for one image file.
The image file contains all 6 faces of the dice with white dot on red.
For simplicity it does not have any lights or cameras, please use your default light or camera from your application.

You can get the files here at
