Note
It's important to understand that ClothFX is
not designed to be a “one sim for every
occasion” dynamic. In other words, you can-
not assign it to your character's clothes and
expect the same settings to work flawlessly
in every situation. ClothFX is only a simula-
tor and its results will vary depending on
what you're asking it to do.
There is a bug in LightWave (confirmed in
versions up to 8.0.1) that causes ClothFX to
calculate parameters improperly if they're
entered in the “wrong” order, but it will cal-
culate them correctly if the scene is saved,
reloaded, and calculated again. Hopefully
this bug will be fixed in the next revision of
the software. But for now, be aware that this
problem exists. If you change a setting and
calculate, but are unhappy with the results
and revert back to the original settings only
to find that the object no longer deforms like
it did before, you're experiencing this bug.
Save your scene, clear Layout, and reload
the scene to work around the problem.
You'll notice that the tube is the only object
in the scene. Technically speaking, this vio-
lates the principal law of the Dynamics
Community, as there are no opposing
dynamics to which this object is account-
able. Under normal circumstances, we
would correct this by adding a social
dynamic such as Gravity. But in this situa-
tion, we can avoid the extra trouble of
setting up an independent Gravity object
and simply use the Gravity setting available
in ClothFX.

Due to a bug in ClothFX, I cannot walk you
through the
individual
application of each
setting, but I can walk you through the
group
application of specific settings. And
again, keep in mind that these settings are
described in detail in the manual and online
help system.

Bring up the Object Properties panel
for the Skirt. Click on the
Dynamics
tab and choose
Cloth
from the Add
In the
Basic
tab of the ClothFX prop-
erties, select the Fix pop-up menu and
choose the
Fixed/
pointset
option. The
Fix option allows you to
choose the points that
will
not
be affected by
ClothFX. All of the
points in the object
except
those in the skirt
were added to the Fixed
selection set. By choos-
ing that selection set
here, we are telling
ClothFX to ignore the
rest of the object and
focus solely on the
skirt.
