(This has the effect of “flattening” the top
of the smooth shifted area, making the edge
of it nice and sharp. This is one of the ways
you can make a sub-patch model have
“crisp” areas of definition. It's not quite as
elegant as setting a value of +100% for the
SubPatch Weight setting for the desired
geometry, but it is a popular trick. Moving it
just that little bit means that the points
won't get eliminated if you were to do a
Merge Points somewhere down the line.)
Note
For the rest of the topic, whenever we
smooth shift a sub-patch, let it be under-
stood that it is with an Offset of 0, a Max
Smoothing Angle of 0, and a Scale of 100%
— just as we've done for all the smooth
shifts so far in this chapter.
10. Next, use the Smooth Shift and Move
tools on the two wing polys to get the
preliminary shape of the wings.
