hi this is Orin zoker and on behalf of
Dan eberts welcome to this quick
overview on how rubberized it works
we're going to start with an image in
this case an awesome vinyl figure
contributed by the very talented Nathan
urvich and I've got it doing a quick
slide
in next we're going to place our puppet
pins
down select the
layer and just using the default
settings click
rubberize
and that's it pretty
simple now we're going to make some
changes I'm going to go select the pins
on his
ears change the
materials make it sponge and click
rubberize it again and we get something
like
this now I'll change the
speed and it gets more
subtle and I speed it up
and it gets kind of
crazy okay now let's change the move
I'll have it doing a drop down from the
top and I'm going to clean the
expression on the pins of his feet by
selecting them and clicking clean and it
looks like
this okay so what just
happened what's going on is that
rubberize it is displacing the puppet
pins based on the acceleration of the
layer relative to the composition that
means it can react to layer changes in
position rotation and scale or even to
motions inherited from a parent layer
how rubberize it reacts is a complex du
of many factors which include the speed
and interpolation of the key frames in
the motion the amount and position of
the puppet pins the type and mix of
materials you select the placement of
the pins you don't apply materials to
the chaos the formula and the position
position of your Anchor Point all of
which goes to say there's a lot of
things going on and the easiest way to
figure it all out is to just go ahead
and try it the UI is built with
experimentation in mind changes are very
quick to make and apply so instead of
reading the manual the best way to learn
it is just to sit down and play with it
that said let's break down the different
sections in more
detail we'll start with puppet pins even
though they're technically not in the UI
they're located in the upper menu if
you're working with something that needs
continuous rasterization you'll need to
pre-op it first otherwise you can apply
it directly to the layer
itself materials are presets that come
loaded with rubber isit the materials
are broadly arranged in least to most
bouncy but there's variations so it's
not exact you can experiment with your
own settings by clicking custom in the
drop- down box and playing with the
settings let's define those frequency is
the bounce frequency in oscill ation per
second Decay is how fast the
oscillations die out and amp sets the
amplitude of the
motion the chaos feature adds a random
element to the
material every time you hit the
rubberize button it'll give you a
different
wiggle if you don't like it the first
time keep
trying the two formulas are variations
on the algorithm Dan wrote to create the
effect each has its strengths and
weaknesses the formulas differ in the
way they relate to the Anchor Point
formula a is hinged to the Anchor Point
and formula B pretty much ignores The
Anchor Point one key difference between
them is that b needs clean pins or un
rubberized pins to act like an anchor
giving the other pin something to pull
against formula a does not but it can
also benefit from them depending on what
you're looking
for if you see the layer just kind of
bouncing around not deforming that's
pretty much telling you to put down at
least one clean

pin there's a lot more to the rubberize
button than meets the eye it actually
applies to rubberize it in three
different ways depending on the
situation one if no pins are selected
and none have been previously rubberized
then all the pins will be rubberized the
second if only some pins are selected
only those will be affected the third
thing to keep in mind is that once you
have initially applied rubberize it
there's no need to reselect pins to make
the changes rubberize it will see which
pins have Expressions applied and will
only change those pins from that point
on this will save a lot of time
selecting and deselecting
pins clicking the clean button will
remove all the expressions from all the
pins that have Expressions applied to
them if you select specific pins then
only those pins will be cleaned make
sure you get to know the different ways
that clean and rubberize work it's it's
pretty simple but it will be key to
controlling rubberize it and saving you
a lot of time and energy when you click
on bake it'll turn the Expressions into
key frames this will really come in
handy when you're dealing with a lot of
individual letters if you do decide to
do it I suggest making a duplicate of
the comp first before you go ahead and
bake
it so that's it the basics of what you
need to know to get rubberize it up and
running good luck and happy
