014 Dynamesh Resolution Part 2 Video Lecture | Zbrush: Create Realistic Modelling - Professional Skills

it's kind of round out the finishing
right like kind of finishing the brush
section the basic brushes and what you
can do with them and then finishing out
the basic dynamesh functionality we're
gonna kind of wrap this up and by the
end of this you should be able to create
like kind of like what I've done but you
should be able to create a creature or a
head or any number of things just based
on the stuff you've learned just with
basic brushes and basic dynamesh in
navigation and up to this point you
should be pretty fairly well versed
enough to go in there just make
something so let's go ahead and
initialize ZBrush again or if you're
starting new you can just start ZBrush
over again and I'm gonna go ahead and
grab a cube 3d drag it out make it a
polymesh3d go hit X to go across X
cemetry here going to geometry and just
right up right up at the front turnoff
project turned down blur resolution is
fine hit dynamesh so now we're sculpting
with dynamesh and I can use my clay
brush here to knock down these edges so
I'm gonna hit on alt and I can kind of
just use a clay brush to kind of knock
down the sharp transition edges here
making smooth if I want to and control
dragged and clay brush and then I go
back to my standard brush and if we open
up the brush menu here these are the
ones I've last been using so I can go to
my standard brush here kind of dig out
my mouth area I can use the clay brush
area to kind of build this up and I'm
gonna go and actually do a head to
caricature demo after this which would
be a little bit more focused and go into
a little bit more stuff that's specific
to sculpting head demo stuff but done
sculpt this out so we've got a basic
kind of head shaped thing going on here
just using our basic brushes we've
learned standard brush brush clay brush
let's talk about a little bit about
resolution and how it affects dynamesh
and how scale actually affects that so
right now our object is you know about
the size of a ZBrush primitive because
again we started with this cube now if I
see if I take another object and I make
it really small and use the same
resolution you're gonna see what happens
so actually what I'm gonna do is we're
gonna do a little sneak preview of a
subtools I'm I take this sub tool open
that up and I'm hold on shift so I have
my geometry menu open and myself
menu open and with this one selected I'm
going to hit duplicate and that's gonna
make me two copies so now you can't
really tell that because of right on top
of each other but if I want to I can
actually select this one and just to
keep it simple I'm not gonna go into
transpose just yet I'm gonna go all the
way down here to deformation I'll hold
on shift open that up and I'm going to
use this offset in X I'm just gonna drag
that over to the right so I'm actually
offsetting it a hundred units and I want
to offset this again another 100 units
and another 100 units just to kind of
move it over to the side basically as
all I'm doing so now I've got these two
objects and they're actually if I go all
the way back up here to the top of the
subtool these are two different objects
if I click on their name here and again
this is just like a little sub tool
sneak preview we're not going heavy into
it yet but just kind of get you feeling
around in here so this object is this
one here it's slightly highlighted and
then this one is this one here it's
slightly highlighted when I select it
and right now they are both pretty much
the exact same object so I have poly
mesh frame turned on and just click
between them they're pretty much the
same right so they glare up the second
one here and I go all the way down here
to the dynamesh and the resolution is at
128 so if I control drag the resolution
is still the exact same and if I make
this smaller so I'm gonna make this
smaller actually go all the way back
down here the deformation menu again and
the size 1 I'm going to drag all the way
to the left and then I'm gonna drag it
all the way to the left again and then
I'm gonna offset it just to kind of move
it out to the right so you see I can
make I'm making it smaller and smaller
and then I'm moving over to the right so
I haven't dynamesh yet so right now it's
got the if we select between those
things so this one has 73 thousand
active points and I click this one this
one has 71 thousand active points or
about the same resolution about the same
size they're slightly different because
I move this one over but for all intents
and purposes they're the exact same
thing however when I click the second
one and I have dynamesh turned on at a
resolution of 128 if I control drag to
read dynamesh you're gonna see my active
point to drop to 5000 and if I select
this top one again you know this one's
still gonna be at seventy one thousand I
read ina mesh this one okay now this
one's at 73 and but then I select this
one and it's a for the resolution of the
dynamesh is the same for both so if i
click between these let's see if we can
actually see it
not really but you just trust me if I
click this top one resolutions at 1:28
dynamesh I click this bottom one
resolutions at 1:20 other dynamesh I'm
gonna go ahead and merge these down so
I'm gonna select this top one and don't
get confused and try and get into
subtitles too deep right now we're gonna
get heavier into sub tools in a bit but
just the basics I'm gonna grab this top
one open up the merge sub sub menu under
the sub tool menu and click merge down
he's gonna merge these both into the
same sub tool here so this is all just
one tool now they're both in the same
thing and that control drag because my
dynamesh is a resolution 128 there are
going to be the same now if I trip now
again this one's still at like 4k this
one's at 70 K but they're both the same
object now but if i zoom in you're gonna
see what's happening is these squares
that make up this dynamesh are the exact
same size so the resolution is telling
the squares how small to be but when you
have these sized squares on a small
object it's gonna seem like a lot less
resolution and these sized squares on a
very large object just to demonstrate
this a little bit more I'm gonna go
ahead and append so I just click this
little pin button I'm going to append a
cube and with this cube selected I am
going to move that out so deformation
and I'm going to offset that negative so
we're again we were we were doing is
doing positive X I'm doing negative X
offset I'm just going to do that a
couple times it's gonna move that out to
the side here here we go and this one
I'm gonna go geometry dynamesh
resolution 128 turn off blur turn off
project and turn down a mesh on so now
these are all gonna be the same size
square so if I click between these two
we zoom in the squares are about that
big
the squares are about that big however
if I take this cube and we go size right
to make it really big we'll do that
twice and then we'll do offset over here
to kind of bring it back into our view
here there we go and now with dynamiter
not only control drag again it's gonna
take a long time because what it's doing
is actually this is actually three
million polygons now because it's this
big these squares are the same size if I
merge all these down so going to merge
this head
down merge down and then we look at
these I'm gonna hit ctrl W to kind of
make them all one polygroup here and we
zoom in and look at the size of the
squares the square is about the same
size as this square so they're all the
same resolution they're all resolution
of 128 however this thing over here was
like 3 million I'm gonna head and hit X
to turn out that symmetry and this was
seventy thousand and this was four
thousand all the same dynamesh
resolution but this one it seems like
you can get a lot more detail on it
because it's a bigger object so the
bigger the object the more resolution
sized squares it's gonna have on it as
opposed to this object as opposed to
this little object here so all based on
resolution and well all based on scale
based on the exact same resolution so if
I take all of these and do like a 32
resolution dynamesh and control-drag and
then turn polyframe back on all of these
squares of the exact same size but this
one barely has any detail at all because
it's so small this one's still gonna
have plenty of detail because it's so
large so just something to keep in mind
so actually what I'm gonna do is let's
go ahead and undo this all the way back
to where we just had the 1 skull here
turn off poly frame control drag now
let's say I'm working on this thing at a
resolution of 32 just to kind of block
it out and we've talked about this
before already so we're gonna turn on X
and we're kind of blocking this out if
you want more resolution as you're
working and again I would say for
something like a skull or something like
a creature I would say start low like a
3d sketch just to make sure your forms
are how you want them and then once
you're kind of ready to start moving up
and worrying about not poor detail but
making Mickey maybe making more changes
that are a little bit smaller in size
but as long a mean make sure that your
forms are what you want first make sure
those are pretty solid and then up your
resolution so it's like okay this is
what we want then you can go in here and
change this to like 64 and I'm just
doubling and then you can start you know
refining this so we've talked about this
before and of course you know you we
might get into stuff about where you'd
maybe want to scale stuff in order to
get more resolution like I showed you
just previous to this but I don't think
it'll be really
all that relevant for most basic type
things so you can change your resolution
over here and just keep in mind that
scale does play a factor when you're
talking about dynamesh resolution
