Squeeze morphs
The idea here is that we're familiar with the use of magnet deformers to balloon meshes outward, but if we put this principle in reverse, we can create indentations. Create a magnet for the Right
Collar. The Base will have the following settings:
Scale 13%
xTrans -0.046
yTrans 0.513
zTran 0.001
Enter these settings for the Magnet:
Scale 20%
yTrans 0.240
zTrans 0.370
Finally, enter these settings for the Mag Zone:
xScale 15%
yScale 76%
zScale 76%
yTrans 0.134
zTrans -0.095
Scale 13%
xTrans -0.046
yTrans 0.513
zTran 0.001
Enter these settings for the Magnet:
Scale 20%
yTrans 0.240
zTrans 0.370
Finally, enter these settings for the Mag Zone:
xScale 15%
yScale 76%
zScale 76%
yTrans 0.134
zTrans -0.095
The figure above should show the results, a weird looking pinch outward. Before you go any further, parent the zone to the magnet, because you'll be moving these as a set.
