Here is the first shot of my UV mapping progress on the KTM RC8 Model.

The colored pattern is simply a test pattern. Randomly selected colors and a matrix of numbers, showing both stretching and orientation. If any numbers are reversed (as in mirrored) then that shell of the model needs its coordinates reversed. If any of the numbers or grid lines are stretched too much, it will be hard to put things like logos or pin-stripes on that area. It’s essentially a visual stress gauge for texturing.
