Blender 2.7 Tutorial #62 : Face Texture Animation Rig #b3d Video Lecture | Learn and Master: Blender (English) - Professional Skills

I'm a little teapot short and stout this
is my handle this is my spout when I get
all high I guess we're ready to get
going cue the intro welcome to part 62
of a VCS 90s blender 2.7 in this video
I'll be showing you how to create a rig
for a face setup and instead of actually
just having a modeled face this is a rig
which will let you animate a character
talking but only have the texture change
different versions of mouths and eyes if
you have not seen the last three
tutorials no tutorial series in part 59
part 60 and part 61 of this blend 2.7
tutorial series I should try to actually
create this Lego character from start to
finish
including the modeling including some
really detailed work in beveling and
creating materials and depth of field
blur so go ahead and check those out to
be linked to those in the description
area below this video now for this video
I'm going to be giving you a few files
you can actually find in the description
area below that you can download for
yourself to follow along the first
follow be a blogger file that contains
just the head of this Lego character
complete with the yellow material on the
head but not the rest of the body so you
can at least follow along with the head
the other two files that you can
download are the texture files of the
mouth shapes in a grid and the eye
shapes in a grid and I'll catch the eyes
in just a second but here is the grid
that I made actually drew these in a
vector graphics program called Inkscape
which is a free open source program that
you can use to draw a vector graphics
and as you can see I have mouth shapes
or mouth poses for all the different
sounds that a character might make with
their mouth like the a or a shape of the
mouth there the V or F so or the R sound
the T sound or s sound the or so as you
can see like the L look kind of L shapes
so we have basically all the shapes that
we would need including just some sort
of angry and grinning and upset and
jaw-dropping and smiling poses as well
so this is the sheet
made in Inkscape and then laid out in
Photoshop onto a grid that's evenly
spaced what's important here is that the
texture is in a square so I have 16
different bells here of course you could
make 25 if you want to make a 5x5 graded
set of a 4 by 4 grid that will allow you
more mouth poses and in the next picture
I have the eyes I have fewer eyes here
but again they're laid out in a 4 by 4
grid I have the round eyes and then just
sorts of different emotions of eyes so
closed eyes and kind of squinty eyes and
angry eyes and unimpressed eyes and
happy eyes and sort of just semi happy
eyes so I have a lot of different
options to choose from let's go ahead
and press escape and jump back into
blender now just to add textures to an
object is not very difficult like an
will be using nodes here so if you want
to follow along you can download the
files in the description area below the
bugger file and the two texture files
let's go ahead and get started the first
thing I want to do here is I want to
select my head and press tab to go into
edit mode I'm going to segment off the
different parts of the head or the eyes
gonna be and where the mouth is going to
be so I'm going to go to edge select
mode I'm going to zoom in here and I
want the mouth I'm going to hold shift
in edge luck mode to select the edge of
where my mouth texture is going to be
I'm going to go and select basically for
out from the middle and then I'll go one
down where the head just starts to curve
down and I'm holding shift and right
clicking to get all these so this is the
area in which the mouth is going to
exist so what these edges selected I'm
going to mark a seam this is how you do
UV mapping so I'm gonna press ctrl e
unlike keyboard I'm going to say mark
seam control it brings up your edges
menu and then mark seam don't confuse
that with Mark sharp it's mark seen
great when you mark a seam the edges
become kind of that's red orange color
let's go ahead and mark the seam for the
edge of the eye section so I'm going to
select just these edges here believe it
or not the eyes and Lego character are
only about halfway
approximately up the head because there
could be hair covering up most of this
area so the eyes actually are bit lower
than you might think I'm going to mark
this as the perimeter of
the I section so control e mark seen now
the first thing I do actually here is
make a UV map because I'm going to
actually have two UV maps associated
with the same mesh this is the first
time that I've ever done this in this
video series let's go ahead and take a
look under the object tab with the head
selected and edit mode of course we have
a section here called UV maps and we're
actually going to have two here but what
I'll do is go into face select mode I'm
going to make the mouse one first so I'm
gonna put my mouse in that area in face
lock mode and press L that stands for
linked and as you can see we have that
area selected I'm going to press u and
then unwrap right there and that will
make a new UV map right here now I'm not
going to use the same UV map from my
eyes going to name this one first I'll
double click in there I'm going to type
UV mouse great I'm going to press this
plus to make a brand new UV map I'll
press a B select the mouth section I'll
press L in face lick mode to select the
eye section and with the new UV map
selected I'll press u and unwrap and
that will put the eyes in this unit and
I'll name this one UV eyes great so
let's go ahead and take a look at these
UV maps I've got several windows here
I've got a no-doubter window my 3d view
and a second three of you I'm gonna
change this one over here into a UV
image editor window right there as you
can see the eye sore just unwrapped to
the bottom here and the mouth unwrapped
if I select I press a and then press L
to select the mouth section just to the
bottom and it fills up the entire space
let's go ahead in this window and open
so I'll go to open and to my desktop
I've got the mouth layout with a number
16 because there's 16 mouths there and
as you can see this unwrapping is way
too big and it's sort of crooked what
I'm gonna do here first though is make a
new copy of my yellow material that
includes this mouth texture but I'm
gonna scale this down in other words the
faces here down to only cover one of
the Mel's let's go ahead and make a copy
of my yellow material I'll go up here to
the materials tab and I'm going to go
back into object mode I'm gonna make a
new slot in this area right now with
this head selected I have one material
and one material slot on this object so
I'm going to make a new slot and I'm
going to put that same yellow material
into that second slot but I'm gonna make
a copy of it that has the mouth texture
above the yellow on it so we've got a
second slot selected I'm going to add
the yellow material as you can see here
I have this number four that means four
objects including sub objects sort of
the two hands the head and the head has
two so it's four in total I'm going to
press this little plus and with this
second thoughts material selected it's
going to make a copy of the other
material which we can then modify to add
on top of the yellow the mouth textures
with the transparency so I'm going to
name this one yellow - mouth and now I
can customize the node of this but what
I'll do first actually is with your limo
selected I'll select my mouth and click
on a sign so now the mouth material
which is right now no different than the
original yellow material is on that
metal section let's go ahead now and
customize these nodes to add the mellah
texture and so to do that I'm going to
take my original yellow material and I'm
going to layer on top of it using a mix
node a diffuse texture that has this
image texture on it so I'm going to
press shift a on my keyboard I'm going
to add in a shader it's going to be a
mix Eider I'm going to put that right
there so what happens after the yellow
material is finished I'll press shift a
I'm going to add a shader it's going to
be a diffused some normal color shader
I'll plug that into my mix shader'
as you can see things are happening down
here it turned white because this color
here is white I'll press shift a I'm
going to add in a texture an image
texture and I'm going to plug that in of
course this is going to be our mouths
texture notice how it the mouth and eye
images are PNG image files I have a
checkerboard other words transparency
around them so there's no white that's
why I chose a PNG image let's go ahead
and open that image just by clicking
and selecting mellows layout 16 and as
you can see it's giving me sort of what
I want at least in terms of how the
layout here is it's putting those images
there but the transparency is not
working properly and that's because I
have to plug the alpha here into the
factor of this mix shader' up I can't
get with a noodle as you can see I have
four little mouths and I can scale this
down over here before I scale this down
over here though I'm going to flatten
these edges out and this is a big
problem for people unwrapping in 3d in
many different 3d programs including
blender they don't turn out straight in
terms of with the lines on the x and y
axes so why not do and there are plugins
or add-ons and blender to do this better
but I'm not going to use the add-on I
can just quickly do this I'm going to
hold I'll press a actually deselect all
I'll hold alt and right click on this
edge to select all of those vertices now
I'll tap s and then up and down is Y and
0 and enter so s Y and then 0 and then
tail do the same thing again a to
deselect I'll hold alt right click sy 0
enter that flatten that out it's like
that one with Alt + right click sy is
your enter I'm going to do these ones
now I'm going to flatten these side to
side on the x-axis so s and then X and 0
enter over here SX 0 enter I'm just
going to do this very quickly
okay so I've got my a UV map all squared
out I'll select it all with the a key
I'll tap s and because I know this is a
four by four grid I'll tap 0.25 and
press ENTER that way I know this is now
0.25 it's really drilled science I'm
going to put it on the default melt pose
which in my case is just my decision is
the just happy metal so I'll put it
right up there I'll zoom in and put it
right at about the right spot
I might have to adjust it later on for
up and down but for now I'm looking how
far away that is and that is looks
pretty good to me good as you can see
it's on there now now in terms of the
animation that you saw to the inning of
this video this is all I did for the
melt material am I going to go actually
almost it's almost as much as I can for
this material I will get to the little
plugin right there in a few minutes but
what I'm going to do in this video is
actually make the mouth material shiny
because in the animation that you saw
emails were just diffuse on top of a
glossy material and I didn't like that
so how you can fix that is this is the
melt that's being kind of put on top of
the yellow material but it's only
diffuse I'm going to fix that I'm going
to press shift a I'm going to add a
shader it's going to be a mix shader'
right there I'll plug it on top so in
between this mix shader' and the diffuse
mouth texture and I'm going to add in a
glossy shader so add shader and glossy
I'll plug that into there and as you
know as you can see it's sort of
becoming gray it's reflecting the gray
of the world I think everything has for
now everything has index of refraction
and this is plastic in fact we already
have the fernell note so I'm going to
reuse that I'll plug that into this mix
shader' which will blend properly the
glossy shader and a few shader so that
you get the reflections in the right way
looks pretty good let's go ahead and do
the same thing for the eyes now I'll go
back into object mode here I'm going to
select my yellow material I'm going to
make a new slot on the head and it's
empty right now I'm going to add that
same in fact I'm going to make a copy of
yellow
mouths so I don't think we do all that
node work so I'm going to add um up a
new slot I'm going to press this little
plus to make a new copy of it and as you
can see it has user 1 now I'll change
this to eyes I'm going to assign that to
the eye faces so I'll select the eye
faces and click on a sign I'm going to
change the material here or the texture
here the image is still set to mouth
I'll change that too and I don't have
the image yet so I'll bring that it I'll
click the little folder and my desktop
eyes layout 10 there's 10 eyes there
were 10 eye pairs there and now
hopefully if I click on a sign this is
where things get a little bit messy in
blender and I'm not quite sure if it's
just because of my lack of knowledge
about using multiple UV maps on the same
object but if I go to the object data
tab you can see that now there are two
UV maps and only one can be set to
render at a time so only one control to
render at a time now we can solve this
sort of it's been a little bit buggy for
me bye and I'll go back to the material
tab in the yellow mouth texture I'm
going to tell this image texture to only
use the mouth UV map in other words this
UV map and I'll do the same thing for
the eyes let's go ahead in our materials
for the mouth I'll press shift a I'm
going to add a input UV map node and
I'll put it right there and I'll plug it
right into the image texture so this
image texture knows which UV map to use
it's going to use them both and then I'm
gonna select the eyes and the same thing
here shift a input UV map and I'll plug
that in whoops plug that in there and
I'll use the eyes now I still don't know
why it's not working at this point but
it will work once we use the modifier to
make the animation work but what I could
maybe do at this point is try using
under the object data tab is going to
UVA
see if those go back and forth but they
don't so it will work momentarily if you
render it out I'm not sure if it'll use
the eyes right now if the eyes will show
up we have to do now is create our rig
to make the UVs slide around that means
if I go into edit mode and I select on
the object tab the eyes layout and then
I'll open up the eyes image there and
tap oh I know why it's not showing up
I haven't scaled these down 0.25 to
scale that down with the S key and then
I'll move that up to Rea there that's
good to me so now I have the eyes about
in the right spot and you can always
adjust these later I'm gonna just move
these little bit over so they're
centered roughly looks pretty good to me
okay let's go ahead and create the ring
that'll let us actually slide around
these UVs now you can't actually animate
you v's directly but there is a modifier
it's called and I'm going to go back
into object mode and select the head and
go to the modifiers tab right now we
have one modifier on the subject it's
just subsurface smooth so the object but
if I go to add modifier there's a
modifier called UV warp which will get
the job done nicely for us this is the
perfect modifier to make a animated
texture on a characters face let's go
ahead and add it with the head selected
I'll go to add modifier and UV warp now
the way this works is you're going to
define how much you're sliding around
your UVs how much you're sliding around
the unwrapped faces based on the
movement or the distance between two
objects so we're actually gonna be using
bones here but not to distort a mesh
rather to just have a distance between
two objects what I have to do here is
I'm going to go to my front view and
this would I'll make this one a little
bit bigger so we can work in it I'm
going to press shift to see to put my 3d
cursor back in the middle of my scene
I'm gonna press shift a I'm going to add
a plane in fact I'm going to add two but
I'll just make one fernette will copy it
later this plane needs to be unwrapped
so I'll press tab to go into edit mode
and then press
you and unwrapped and that will actually
unwrap it over here in my uv/image
editor window I'll go back into object
mode I'm going to scale this down
because right now it is 2 centimeters by
2 centimeters and I only want to be 1 by
1 if you have not changed your units in
your file to the metric system then
it'll be just one letter unit by one
butter you know but I used metric so
I'll press s and then 0.5 and I'll press
Enter so s 0.5 and then enter will make
it down just one the scale is now off so
I'll go to and this is very important
I need my scale to be set to 1 and not
0.5 it actually knows that it's not the
right size that I started off as so
we'll go down to object and apply and
scale there we go
I'm going to subdivide this square up
and then apply the mouth texture and
I'll make a copy and put the eye texture
on the other one this is going to be
sort of our control center for animating
the mouth in the eyes so let's go ahead
and apply the texture onto this object
right now I have only two windows up I
believe now I've got three I've got my
unloaded or window here so I've got this
a plane unwrapped I need to add a
material to it I'll go to my materials
tab click on new it adds just a default
material it's diffused so I'll press
shift a I'm going to add a texture it'll
be an image texture I'll plug that in
I'm going to open up all my mouth
texture so right there as you can see
there are my mouths they look funny
because of the transparency that isn't
there so I'm going to press shift a I'm
going to add in a shader it's going to
be a mixed shader and we're going to mix
this diffuse image texture with a
transparent shader so I'll press shift a
I'll add a shader it'll be a transparent
shader I'll add it right there I'll plug
it into the shader here it made it all
sort of transparent but I'm going to
plug the Alpha output of the image
texture into the factor of the mix
shader' and i believe i have to reverse
these now to get the way I want it and
so now we can see our mouth texture is
very nicely let's go ahead and duplicate
this and make these square for the
eyes before I do that though I'm
actually the subdivide up this square so
I'm go into edit mode and as you can see
it's just sort of one square or one
polygon um with its all selected in edit
mode I'll press W I'll bring up my
specials menu and then subdivide I'm
going to make seven cuts the reason why
I'm making seven cuts is I want a
vertice I'll go into my front view so
you can see this or if my top view
actually we want a vertice right in the
middle of each mouth or approximately in
the middle of each mouth because we want
to actually snap our bone controllers to
these locations so I have vertice in the
middle of each into the mouse but what
I'm going to do is I'm going to get rid
of the extra edges I can hold alt and
right click and select that edge loop
hold alt and shift and get these ones so
I'm going to get all the edges that
don't run through the middle of a mouth
so I believe I have all those selected
I'm going to press X and I'm going to
dissolve edges right there and make sure
you have dissolve verts so now I have
edges running through the demos and no
extra edges at all perfect let's go back
into object mode I'm going to duplicate
this plane so I shift E and then why put
that down there
this object now has the same material
but I'll press this plus and I'm going
to make this one just tab I don't care
about the name actually
but now we've made a different copy of
the material I'm going to change what
material texture it has I'm going to use
the eyes right there and as you can see
now if I go back into edit mode I still
have a vertice because I evenly spaced
things out in Photoshop between each one
of the sets of eyes and there are extra
speckles which does not matter let's go
ahead and add some controller bones for
that and I'll go back to my head object
just for a moment we have this UV work
modifier we don't have any from our two
objects we're going to add bones for
that what I'll do here is on my mouth
plane I'm going to go into edit mode I'm
going to select the vertices Altan out
the same mouth that I unwrapped to over
here with my mouth texture
I put the faces that I unwrapped over
this default mouth so I'll do the same
thing over here I'm going to
like that same vertice I'll press shift
s I'll bring up my snap menu and I'll
select cursor to selected right there
because it's selected I'll go back into
object mode I'm going to add a armature
bone there so I'll press shift a I'm
going to add a armature single bone
actually what I'm gonna do is I'm going
to undo that control Z I'm going to
select my two planes and I never pressed
our x90 for 90 and then press ENTER to
rotate them up so they're facing me from
my front view that'll make things a bit
easier so I can start adding bones now
and the bones will be upright I have
them flat on the ground before so now
they're facing me from my front view
let's go back into edit mode of the
mouse I've got that vertices selected
shift s cursor to selected back into
object mode shift a armature single bone
will armature now I want to scale this
bone down but it's very important that I
don't just scale it down an object mode
I'll press tab to go into edit mode and
now I can right click to select this
tail nub of the first bone that's in
this armature and drag it straight down
again in edit mode because we don't want
to scale the entire armature just one of
the bones that's very important I'll
make that one about that big I'll press
shift a Wasel and edit mode of that
armature and shift a will add another
bone at our 3d cursor I make this one
it's a little bit smaller so now I've
got two bones coming off the exact same
location and one's a bit smaller than
the other under the object tab I'm going
to make them only display as wire so I
can see both of them at the same time
and under the bone tab I'm going to give
these bones and names the bigger bone is
going to be called and the bone name is
right here it's going to be called bone
dot base and then the smaller bone is
going to be called mouth dot target
actually I'm going to change the thing
with a bigger one to mouth dot base
perfect I'm going to go back into object
mode of the armature I'm going to give
under the object tab the whole armature
a name object name not an armature name
object name so I'm going to call it our
mature dot mouth perfect what I'm going
to do here is I'm going to now point
that UV warp modifier to these two
separate bones and we're going to
animate only the target bone in the
bones pose mode and this bone will move
around we can press G and move it around
to the different locations of the mouth
and the UV warp modifier will actually
slide that texture around on the surface
of the Lego person hip let's go ahead
and set that up so I'll zoom out I'm
going to select little Lego head and
then go to my modifiers tab there's the
UV modifier I'm actually going to move
it up to be above or before the subsurf
modifier so now the modifier is
happening after UV warp the from object
is going to be the target so I'm going
to select my armature mouth that's why
we named the object name there and the
bones gonna be called the target of
target and we're going to use the same
armature and the mouth base and we want
to make sure we're using the right UV
map here so I'm going to select UV mouth
so now what I should be able to do when
I'm going to make this window a bit
wider is I should be able to grab just
the target bone actually I'm going to
select the base bone I'm gonna press H
to hide it so we're not put that board
anymore I'm going to grab this target
bone and if I move it around you can see
it sliding around the mouth texture so I
can put it up there and then he's
printing and then right there and then
he's scared notice that it's going to be
hard for me to position these in the
right spot and that's what we made these
vertices in edit mode we can use our
snap tool down here this little magnet
and it's set by default to snap to the
closest
tax what I can do now is grab and I'll
go back into my front view and that's
good enough I'll grab that bone and I
it'll snap exactly to where each one of
those mouths is and yes we could go way
off but we won't so as you can see now I
can put in any one of these spots and
it's a little bit off you can see that
the bottom of the L mouth is getting cut
off so is that one
so what I'll do is I'll go back over
into the uv/image editor window and go
into edit mode of the mouths UV map so
go to mouth and right there and as you
can see the bottom of this melons
getting cut off so I'm going to slide
I'll press G to grab and then I'll press
actually I'm going to press escape and
turn off snapping snapping happens in
all windows at the same time and you
turn it off and turns off in all the
windows so office G and then Y and move
that down just so that that mouth is not
getting cut off that means that the
smile is going to be a bit higher that's
okay though let's go back into object
mode and see how we're doing or any of
the mouths getting cut off I got turned
snapping back on of course that one
looks good that one looks pretty good
yeah I think we're doing pretty good and
you can adjust it so that things are in
the right spot but my texture should be
pretty good for all the mouths once you
correct one of them let's go ahead and
do the same process with the bones and
the UV work modifier for the eyes what
I'll do is I go and select the eyes
plane I'll go into edit mode with the
tab key of course the default eyes are
just the round eyes that's where I
probably unwrap to hopefully I'll press
shift s and I'll put my cursor to that
selected vertice I'll go back into
object mode I'll press shift a I'm going
to add a single bone armature again
we're not going to scale this armature
down we're just going to go into edit
multiple sync tab of course and I'll
grab that top nub of that bone they
could be the tail nub of that bone and
drag it straight down still have
snapping turned on and I'll put it
about there that's going to be the base
I'll press shift a in edit mode still
this will be target I'll press tab to go
back into object mode I'll make sure
that we can see these bones under the
object tab only as wires and let's go
ahead and name these bones I'm going to
go into edit mode of the armature select
the bigger bone and that's going to be
eyes dot base and then a smaller bone is
going to be eyes dot target perfect
let's go into the bones pose mode and
let's associate it with a UV warp
modifier on the head so I'll select the
head go to the modifiers tab we have one
you be more modifier I'm going to type
in mouth for that one so we don't
confuse it with the other one that we're
going to add I'm going to add modifier
UV work we'll name this one UV warp -
eyes and we're the same process here
again we're going to put it before or
above the subsurf modifier I'm going to
select my armature which we didn't name
so let's go ahead and we'll select the
armature and under the object tab I'm
going to give this armature a name
armature dot eyes and I think we're good
to go let's go back to the head and
under the modifier tab there is an
armature called armature eyes the bone
it's going to be the target that's the
first one is a bit backwards you think
you'd specify the base first but you
specify the target first and then to
armature eyes and then the base again
the target is the smaller one I need to
specify though a UV map and I'm working
with it's going to be the eyes UV map
and it's all set up I can minimize it
and I'm going to hide the bigger bone
each and so now if I grab with the
magnet snapping turned on I can then
move this one around and as you can see
I compose the eyes and switch between
the different eyes and yeah you could
probably even mess it up and go to the
edge too but that's the basic setup for
a rig this is exactly the same setup
that I had - a few of the eyes from
animation beginning of this tutorial the
benefit of using bones here and yes you
could use other objects you don't have
to use two bones a base and a target
bone you could use like two empties or
two meshes but the benefit here is that
you can actually create a pose library
to help you animate quickly but that'll
be in the next video in which I show you
how to actually take a recorded audio
clip of dialogue bring it into blender
so you can actually scrub around in your
timeline and hear the audio wherever you
are you can hear it slowly and an
animated mouth to a piece of audio very
quickly this is a very fast process once
you have a rigged mouth set up just like
we have here it actually only takes I
only spend about 30 minutes or so
animating the mouth in the animation you
saw at the beginning of this video so
it's a very quick process to use this
setup that will be it for this video
