UVs and the checkerboard
 

I've only messed around with texturing once or twice, so I don't know much about UVs. I've never used the checkboard but I understand it is to check for skewing or strethching.

Take a look at this video here: http://www.xbox.com/en-us/xboxtv/def...&v=85547&bw=hi (open in IE).

A little before the middle of the video he applies the checkerboard to the model's face, but from multiple angles. I asssume they already had the UVs layed out correctly. So I'm trying to understand why and how he applied from multiple angles. Is this a different approach to the typical UV layout?

Why wouldn't you just lay the UVs out and then apply checkboard to the whole object. then check for skewing?
