hello everybody
in the last video we went
over uh some of the interface of
mudbox uh for instance we looked at the
layers tab
as well as the object list which is the
equivalent of the outliner in maya
where we can see what we actually have
in our scene
and we also spent quite a bit of time
looking specifically at the
sculpt brush and its settings
over here and we briefly looked at
the erase tool and the smooth tool
to very quickly review some of the
material that we went
over you will remember that the w key
will give you a wireframe view of your
mesh
you can toggle it on and off
and you will typically want to use
shift d to up
the resolution of your mesh so that
you'll have enough
geometry to uh to sculpt and model
i'm bringing this up to level five which
gives me
almost 400 000 faces
another thing that i recommended in the
previous video
was to work in layers
because that will give you more uh
functionality it'll give you more
flexibility as you do your sculpting
we looked extensively at the sculpt tool
and you'll remember that it will
pull geometry out however
you can also change some of the settings
over here
for instance we can invert it which will
push the geometry in instead
in addition we can also use the control
button
on our keyboard to get the same effect
so
when i use my brush stroke like that it
pulls the geometry out when i hold down
the control key
it pushes the geometry in
you also learned that you can change the
size of your brush
here i can make it larger
or smaller
in addition i can use the b key on my
keyboard to get the same effect i hold
down the b key use the left mouse button
and i can interactively adjust the size
of my brush
i can also adjust the strength of my
brush here

Watch video from 03:00 - 6:00

if i make the brush weaker i'll get this
effect
if i make it stronger i'll get this
effect
and once again there's a hotkey for this
uh for this functionality and it is the
m key
on your keyboard and if i use my left
mouse button you'll see
interactively how i can adjust the
strength
of this brush
a couple of other things that we looked
at were
the stamp spacing which is found
here and if i increase the stamp spacing
and increase the strength of my brush
i'll get this
if i decrease the stamp spacing the
stamps will
be closer together
closer and if we keep that distance very
small
the stroke will look much more smooth
we also looked at the fall off
here and
the different fall off settings which
can be found here
which will adjust the effect of our
brush
the default has a very soft
peak as well as a soft base
but if we try some of these other fall
offs
we get a different effect for instance
for instance this one has a sharp
peak but a soft base and this one
does exactly the opposite where it has a
very
soft peak but a sharp base
you can play around with these different
fall offs but you can
also adjust
and create your own falloffs
three i'm going to set this back to
something a little more
like the default the default behavior
there
uh another thing that we looked at i'm
going to press w so that we're not
seeing the wireframe on here any longer
is that you can hide and unhide your
layers that's one of the strengths
of working with layers you can also
decrease the strength of your layer or
increase the strength of your layer
and in addition you can create new
layers
i'm going to hide this layer and i'm
going to create a
new layer now remember that the layers
are actually associated with
the resolution that you're currently

Watch video from 06:00 - 9:00

working in
and what i'm working in now is
my highest resolution we'll take a look
at that again in just a moment
now that i'm in a new layer and i've
hidden
my original layer here we'll take also
a very quick uh look and review
at the mirroring currently it is
off but if i turn on the x mirroring you
can actually
see the axis that it is going to
mirror it on or the y-axis or the z-axis
for example
we'll try the x-axis and
with mirroring on
whatever i do on one side will happen on
the other side as well
you can explore some of the other
mirroring as well
another thing that we looked a lot at in
the previous video
were how to work with layers and it's
very crucial to understand
how to work with them to use mudbox
effectively
so i'm going to activate once again my
other layer so now i have these two
layers on top of one another
you see i have this layer here and this
layer here
currently i have my layer 2 selected and
what i'm going to do
is enable my erase tool
i'll make my brush a little bigger by
using the b key
and i'll erase and you can see
that in fact when i erase it only erases
what is actually
in the layer that i currently have
selected
you can see that i can't erase this
these strokes here because they are not
on this layer
if i want to erase these strokes as well
i would need to select
that layer and then i could erase
the sculpting that's on that layer as
well
and the other thing that's very
important to understand when working
with these layers notice that
uh here there's the number five and the
number
five meaning that these layers are
associated with my
level five of this mesh and you'll
remember from the previous video that
you can use the page up
and the page down keys on your keyboard
by doing page down i'll go to my lower
levels
level four level three

Watch video from 09:00 - 12:00

level two level one and so on in fact i
can go all the way down to level 0 here
where i have
only 384 polygons
if i want to go back up to my other
levels i
simply use the page up key
but notice that when i'm on layer 4 i
cannot
work in either of these layers
we have this little icon here indicating
that
i cannot sculpt on that layer right now
if i want to do any sculpting on layer
level 4 which is what i'm at now i need
to create
another layer for it and now i can
sculpt on
that layer
currently i have my erase tool selected
let me select my sculpt tool
and as you can see i can sculpt i still
have
mirroring on remember when you don't
want to mirror any longer
make sure to turn it off so now i have
the third layer i can hide
unhide it i can use that layer when
i'm on level four of my mesh but if i do
the page up and go to level five i can
no longer work on level four
however i can work on either of these
two layers
the other way besides using page up or
page down to
cycle through your layers would be to
come over here to
mesh where you can step up or you can
you can step the level up or you can
step the level down
here you also see the hotkeys of page up
and
page down before wrapping up
uh this quick review i am going to go
over to my object list
this shows me everything that is in my
scene so i have four cameras i have a
light i have a
default material and i have my sphere
and if i click on this plus symbol here
you will see
all the different levels of my mesh and
in fact this is one of the very powerful
features of mudbox is that you're able
to work
on a single model
but at different levels sometimes it's
going to be easier to work
on your model at a lower level and
sometimes when you need
fine details it's going to be easier and
better to work
at a higher level now my
reason for doing this very quick review
is because in today's video we're going
to be taking a look at the rest of the
sculpt tools here
but what you should understand is that
when you know how to use the sculpt
tool here these other
brushes work very similarly
now as i go over these different tools
i'm actually not going to go through
them
in the order that they appear uh it'll

Watch video from 12:00 - 15:00

be a little bit
easier to understand perhaps if i group
them
according to their similar functions
and what i'm going to do first is start
a new scene
i won't save this and once again i will
use a sphere for this demonstration
i pressed w so that i could see the
wireframe here i'm going to return to my
layers
tab here and i'm going to up the
resolution of the mesh so that i can
more effectively sculpt on it
by holding down shift d one
two three four we'll do
uh we'll go all the way up to level six
so that it is more than
one million five hundred thousand faces
quite a lot
of faces but that's one of the strengths
of mudbox is that you're able to work
with very high resolution meshes i don't
recommend using more than what you
actually
need but because of the versatility of
being able to
page up and page down on your mesh to
the different levels
uh you're able to work with very high
resolution meshes
and you can see my wireframe here
and you can see how high resolution this
mesh is
i'll press w to hide that wire frame
and we'll start taking a look at some of
these other tools now
you'll remember from the previous video
that i showed you that if you put your
mouse
over the tool itself it'll tell you what
the tool does
the scope tool lifts the surface as you
stroke over it we're going to take a
look at a couple other tools that work
very similarly
i won't go in depth with them because
basically if you understand the sculpt
tool you'll understand these other tools
as well
so another tool that is very similar to
the sculpt tool
would be the foamy tool found here
and if i put my mouse over it you'll see
that it says the foamy tool is intended
for initial shape
forming rather than for creating fine
detail
it is similar to the sculpt tool but has
a softer feel
and that's really all you need to
understand about this tool
it is the exact same tool as the sculpt
tool
with the key difference that it is a
little bit
of a softer effect that's it really so
one thing i should quickly remind you is
please
do remember to work in layers because
that's going to give you
more it's easy to forget very easy i
forget it oftentimes i forget to create
layers but if you remember to make a
layer before you actually start
sculpting
your results will be much better you'll
have much easier time working with it
so i currently have the foamy tool
selected now
and as you can see it works very

Watch video from 15:00 - 18:00

similarly to the sculpt tool
and in fact all these different settings
here are going to be the same
as the sculpt tool and once again you
can use the b key
and the m key to adjust the brush's
width
as well as its strength
another tool that is very similar to the
sculpt tool
but is actually i think a quite nice
brush here
is the wax brush again i won't go into
it in too much depth because it works
like the sculpt tool
but the wax tool builds up the surface
similar to the way adding clay or wax to
a sculpture would
so let's select that
and
you'll notice it works very similarly
to the sculpt tool perhaps with
just a little bit more of a flattened a
less
rounded appearance
otherwise it works identically to the
sculpt tool and the foamy tool
now one thing to understand about mudbox
when you're working with it
is that when it looks like we're adding
as the tool suggests that we're adding
material
to the mesh but remember that you are in
fact
not adding any additional faces
or geometry to a mesh
when when you're sculpting you're in
fact just pushing and pulling the
material that is
already there
now don't forget that because the wax
tool does work
uh more or less identically to the
sculpt tool
that all those different settings that
we looked at before
such as inverting will also
work you can push the geometry in rather
than pulling it out remember you can
also use your hotkeys for
that same effect so here i am using
the wax tool to pull geometry out
and if i hold down the control key it
will push
it will have the inverse effect it will
push the geometry
in instead
so we've looked at the sculpt tool
we've looked at the foamy tool and the
wax tool these three
work very similarly to one another but
let's take a look at some tools that
are a little bit different and we will
start with
the knife tool i will activate the knife
tool
and as you can see
it creates what looks like a cut in the
mesh
if i increase my brush size
i'll get a bigger a wider cut if i

Watch video from 18:00 - 21:00

decrease my brush size it'll be a
tighter cut
of course you can also adjust
the strength just like you can
any of these other brushes
don't forget if you put your mouse over
the tool itself it'll say what it does
in this case the knife tool cuts very
fine strokes
into a model surface the tool has its
own stamp
image that should be that should not be
changed
now we'll talk about stamps in
the next video
the next tool we'll look at will be the
bulge tool
found here and if we put the mouse on it
the description is that the bulge tool
inflates the area under the brush by
pushing each vertex
out along its own normal
so that's a little bit different than
the sculpt tool that
pushes everything or pulls everything
out or pushes it in depending on your
setting
this one will do something similar
however
it brings the geometry out according to
the face
is normal so in other words the
direction that the face itself
is pointing at so let's take a look at
what we can do with that i'll make my
brush a little bigger
and you can see it looks very similar
but actually there is a subtle
difference
if we were to look at these faces here
uh
each of these individual faces if you
imagined
the direction that the face is pointing
in that's the direction that it's
pulling
the geometry out on
and that is the bulge tool
and also we'll take a look at the grab
tool
found here now this isn't the best
mesh to illustrate this with but we'll
take a look at it
the grab tool grabs a single point on
the surface and allows you
to pull it in any direction
so as an example
i'll activate the grab tool if i put my
mouse
here or maybe here more towards the
edge of it and i pull it out
you'll see how easy it is
to really adjust the shape of
your geometry the form if i make my
brush bigger i'll get a bigger
effect if i make it smaller i'll get a
smaller effect in fact this will look a
little messy you can see how it pulled
it out there
but that is the grab tool to better

Watch video from 21:00 - 24:00

illustrate the grab tool perhaps
uh we should look at a different mesh i
think a different mesh would illustrate
the power of the grab tool a little bit
better so
what i'm going to do is i'm going to
start a new scene
and we will use this human body
now again i'm going to increase the
resolution
at least a couple levels and let's take
a look at this grab tool
very powerful tool a very great tool for
really
making quick big changes to
your models so i currently have the grab
tool activated
i'm going to make my brush bigger
oftentimes when i use the grab tool if i
want to make big
changes to something i'll use a large
brush
here and you can see that
i can really
adjust the mesh and make
large changes very very quickly now
as i've said before use
layers and that's something i forgot to
do i forgot to create a layer here
this means that if i want to erase this
change
i'm not going to be able to so i'm going
to
undo that
and i'm going to create a layer the
other thing
i think i'll do with this grab tool is
turn on mirroring so now
if i make changes to one size side
it'll it'll make the appropriate change
to the other side
of the mesh as well
now remember that you can adjust the
size of your brush depending on the
effect that you need
i'm going to give this guy little short
stubby legs
by increasing the size of this brush and
and there we go this is one of the power
i'd say
what makes the grab brush or sculpting
tool so powerful
is you can see how very very quickly i
was able to
adjust this mesh and make it
into something very different than what
i began with
and because it's on a layer i can
deactivate that layer or reactivate it
i can adjust its strength
or if i need to i can erase the

Watch video from 24:00 - 27:00

the effect
so this video is getting quite long i
think i'm going to break
this up into two videos where i'll cover
some of these
other sculpting tools found here
but the tools that we've looked at today
are the sculpt tool
grab foaming
wax the knife tool
the bulge tool and we spent a little
time using the erase tool as well
i hope that this video was informative
and interesting for
you and i'll see you next time

Part 1 of a 4 part series looking at the sculpt tools in Mudbox. In this video we go over some basic tools such as sculpt, foamy, wax, and grab.
