Welcome to this lesson where we learn more about unwrapping, making seams and specifically for organic
models like ahead and in our case, bones as head here.
And if you don't have this file, you can find it with the course files.
And so you can work from your own from the previous course section on 3D modeling where we created him
or her.
And you can open that up or you can open up mine and follow along.
So what I'm going to show you is also helpful for hard surface modeling.
So if you haven't finished unwrapping the Ghostbuster model, that's fine.
You can use these tools to actually even help even more.
So I just want to wait and to show you these tools until we got to Bones, because it's a little more
helpful for the organic shapes.
So what we're going to do is focus on the head and unwrap that.
So I'm going to go to workspace editing like we've done before.
When I click the head and we can see the UVs are total nightmare.
And with this turned on here, we see we have seams all around the eyes because that's where we did
the kind of edge modeling stuff.
And in theory, when we're looking at unwrapping ahead, we don't want any seams on the front of the
face or we want very few seams.
And the reason for that is simply because that's where we're going to be looking the most.
And we don't want any textures to have any weird distortions around the seams, which is what tends
to happen around seems.
So with that knowledge, what we can kind of deduce is we need to put the seams back here.
We need to unwrap from the back of the head and I'll show you how to do that in this lesson.
So let's turn on the texture so we can see how just how crazy and psychodelic this is and why we need
to make UVs.
Let's turn on the border edges and think, you know what?
Instead of us trying to merge these edges back together and dealing with this mess, let's just start
from scratch, make our own moves with a projection of some kind and then start making our seams.
Otherwise, we'd have to merge all this stuff down for no reason when we could just create our own moves.
And we can do that by going to UV camera based.
And it's just going to use the camera that you have and it's going to shoot them on there.
And you can see where it gets distorted based on now that we moved the camera around, you can see how
distorted that is.
We can keep doing that, whatever.
But, you know, it doesn't really matter.
All we're doing in this step is getting rid of all the seams.
You can see there's no seams now.
OK, so just for clarity's sake, I like to do this from the front view, just so we can see that you
know, the face in the Yuva editor more clearly.
So let's go to camera based now there in the front of you.
And we can see it's kind of looks a little more like what maybe we'd expect it to look.
So what we need to do is unwrap it, because we can see this texture goes all the way through the head
and there's all this stretching here on the side.
So let's unwrap it with the 3D cut tool here.
It's a new tool and my twenty eighteen.
And with that selected, we need to go to the edge mode.
Someone to hold down right click component edge.
And like I said, in theory we need to put the seams back here.
So I'm going to double click this seam in the middle and it's going to cut the head in half.
But you know, like I said, we don't want these teams down the middle here, so we need to get rid
of all these.
And we do that by holding down control and clicking and dragging and we can try to get rid of some of
these seams.
And this is one way to create a scene and I'm going to show you another way, you can see accidentally
double clicked it while I was holding down control.
So it's this way can be kind of useful.
And this tool is very useful.
But in this case of making a scene, it doesn't go all the way around.
It might be a little harder to use.
So let's look at another method that's kind of more traditional and has worked.
And every version of Maya, if we just take cue and go to selection, let's click on where kind of we
want the edge to start, which is maybe high up on the forehead.
And let's go down to the chin where we want the edge to end.
So we double click that it goes all the way around.
Now, we've just made a selection.
We still haven't cut it.
So we need to go over here and cut it so we can go to the cutting.
So and cut the short cut for that.
Also, if our mouse has hovered over the movie editor, we can hit shift X and we'll make the cut for
we hit shift X while our mouse is over the viewport here on the left.
It won't recognize that shortcut and won't cut it.
So just know that.
And so now we have that cut.
But if we think about wrapping this, this, this isn't going to get us very far.
We could actually even try.
Right now, let's go to unfold and hit unfold.
And you can see we actually need to select everything because you just have that one edge selected.
So let's go undo that and go and go right.
Click UVs and select everything.
And now to unfold.
Now you can see where the distortion lies based on our one cut and what we need to do more and why we
need to do more.
We can look at the distortion here as well.
We can see there's quite a bit along the seam and on the kind of more curvy parts of the face.
So let's try to reduce this by adding more seams in here.
So I'm going to undo this just so we can kind of see it back where we were expecting it to be.
And I'm going to go back to the edge mode and I'm going to turn on symmetry because with this texture
on it, we can turn it off and it's easier to see.
But if you want to leave that on, it's kind of hard to see.
If we wanted to make edge cut here, that doesn't go all the way around.
Click here.
And then, you know, I think this is the same edge loop and double click and cross our fingers.
It's actually easier to just turn on symmetry.
You don't have to worry about that as much.
So let's hold on w left click and go to symmetry symmetry.
You can also get to that where we've learned before in the tool settings over here and go down to symmetry
settings and turn that on here.
So I just like to kind of teach shortcuts a little more the further we get along and get comfortable
with this stuff.
So now symmetries on now we just have to go to the center and shift Double-Click.
So now we have that shift ex.
Now we made a cut there.
Let's go to the chin and do the same thing.
So I'll click here and go to the center and shift X with my mouse over on this side.
Sorry, shift X and make a cut there.
And then we also want to make one cut that goes across the back of the head.
So I'll make it up to the kind of biggest protrusion here, which this was a human head.
It'd probably be the ear or something like that.
Someone had shift X, my analysis over here make another cut and now we can try to unfold this again.
But I will say what?
One last thing I want to do is get rid of this kind of inner part of the nose because we're never going
to see it.
And it could add a lot of distortion to the unwrap because it's all one piece right now.
So I'm going to double click it and then try to follow along and edge.
That will not be seen by the front.
So I'm just kind of going in here and following along until I get to that.
So I'm going to hit the cut button here or shift X, you can do the same thing.
And now if we right.
Click, go to UVs, select everything and hit unfold, it should look much better.
And we can see here as well.
You know, the checkers look pretty good.
One goofy thing is just how this is kind of cockeyed and it's not straight and all that kind of stuff.
So if we hit shift and click on any button in here, we can put the option box.
So the one little thing you can do is click back.
And so it's going to pack the unfold UVs as it's done.
So if I hit apply, it should pop back down to the zero to one you've space that we're expecting it
to be in.
So if I scale these down just a touch, I'll get rid of this.
This kind of tells me this is poking out over here a little bit.
So I always tend to just scale it down, just touch and that go off.
So now we can look at the distortion and it should be quite a bit less.
There's still quite a bit I mean, there's still some there, but that's to be expected.
So.
This is a really good start, and, you know, there's no right way or wrong way to to unfold ahead
organic objects, we're really just trying to get the least amount of distortion on this and hide as
many seems as we possibly can so that when we, you know, paint a design for his eyebrows or his mouth
and around his eyes that it's not going to be distorted.
So we have learned how to use the new 3D cutting and so tool a little bit.
But we're going to use this a little more and learn a few more shortcuts with this as we continue to
unwrap the body in the next lesson.
And from there on out, you'll have pretty much everything you need to know about UVs and you can move
on to shading and texturing, which is a little more exciting.
But thanks for watching and I'll see in the next lesson.
