Maya Interactive Groom Uvs

SeanWink

Can someone please explain to me why the UVs for the Linear wire in Interactive Groom look like this when I convert them to Polygons? I should be getting perfect squares on my checkerboard not rectangles. This tutorial doesn't really explain the UVs at 7:30.

It fills the uv space so you don't waste texture memory/can use rectangular maps etc.

If you want multiple tiles you can tell it to make them in one of the settings panels
