U B end/V B end—Resistance to bending. The higher

bend. A cotton fabric might bend more easily than
leather, so a value of 15.0 for both U and V Bend
might be good for cotton, while 50.0 would work
well for leather.
By default, the U Bend and V Bend parameters
are locked together so that changing one sets the
other to the same value. You can set different
values for the two only w hen Anisotropic is off. It is
recommended to do this only for Garment Maker
(page 1–607) objects.

UB-Curve/VB-Curve—Resistance to bending as
the fabric folds. The default value of 0 sets the
bend resistance to be constant. A setting of 1
makes the fabric very resistant to b ending as the
angle between triangles approaches 180 degrees.

By default, the U B-Curve and V B-Curve
parameters are locked together so that changing

different values for the two only when Anisotropic
is off. It is recommended to do this only for

UStretch/VStretch—Resistance to stretching. The
default value of 50.0 is a reasonable value for most
types of cloth. A Larger value will be stiffer, w hi le

Shear—Resistance to shearing. Hig her values
result in stiffer cloth fabrics. Shear defines how
much the individual triangles can deform. If you
were to lay the edges of the triangle out in a s trait
line this value would represent how long this line
can stretch out to. With a high value this length
