Unwrap Faces
The Unwrap Faces
algorithm literally unwraps the model and lays it flat to produce
a distortion free UV template. When using this approach, it
is best to select and map the model in several small portions to
prevent overlapping UV coordinates. This overlap would cause
two or more areas on the model to be textured from the same area
of the image map. For illustration, we will look at two
examples where the entire model was unwrapped, one with the Ruling
Lines algorithm, and one with the Spiral algorithm, to produce
overlapped UVs. Then we will look at an example where the
mapped in small sections to prevent the overlap from occurring.
