How is this blendfile hiding textures? I saw this tutorial on Blender Nation that deal with creating Minecraft animations in Blender.  After following several links, I finally came up with the file and downloaded it.

I could edit the images that were used to texture the models.  However, when I wanted to disable anti-aliasing/sampling, I discovered that the textures are not linked to their objects in the usual way (i.e., through the Textures tab in the Properties panel).  In fact, I have not been able to find any link between the textures and the objects that they adorn.

What is going on here?  Am I just missing something blindingly obvious?
The reason for this is that none were created, the author simply unwrapped the models and changed the view to Textured.

Here is a quick example using the texture I unpacked from the file. As you can see, the cube doesn't even have a material. This is perfectly legit in Blender but really bad practice as it pertains to asset management etc.



Since the objects are already unwrapped, to fix it, just create a texture and change Coordinates under Mapping to UV. For a bit more information on correct UV mapping, see Blender UV mapping error
