Transferring UVs and final model cleanup

00:03

Now because of the simple pattern in this area, it isn't immediately noticeable,

00:09

but we need to keep to the original UV layout because changing

00:12

it will affect the other texture maps like the normal map.

00:15

For example,

00:17

let's quickly bring back the original model and compare.

00:22

OK. So we can see some stretching here

00:25

compared to here.

00:28

We can quickly fix that though using the original model.

00:31

So it's a good thing where you copied it,

00:33

select the original model and then add the edited one to the selection.

00:39

Now go to mesh

00:40

transfer attributes and open the options.

00:44

This tool will copy elements of one model to another.

00:48

So we can use it to copy the UV layout.

00:51

The main setting we need is this one UV sets

00:54

set to all or current depending on the model.

00:57

But all is a safer bet.

01:00

Let's just use world as the sample space because these models are in the same place

01:05

and click apply.

01:07

You may need to rewind to see it.

01:09

But those star patterns moved back to the original position.

01:12

So the UVS are now fixed.

01:15

OK. Let's turn off the texture and continue working.

01:20

I'm just going to speed this section up

01:21

slightly because we are just repeating the process.

01:24

And I don't want the video to drag on and on.

01:27

All I'm going to do is repeat the same process,

01:30

add edge loops to help remove the triangles

01:34

soften the surface normal.

01:36

And then we're just gonna use a relaxed tool again to even out the vertices.

01:41

And then finally use the transfer attributes tool to update the UVS.

01:47

I've spent some more time updating the topology.

01:50

So you can see it's a lot cleaner and will deform in a much more predictable way.

01:55

It's always best to try and make the edges of your model follow natural muscle lines.

01:60

But it's also useful to follow crease areas too when working on clothing.

02:05

Like you can see here around the hips.

02:09

The topology is much better here too.

02:12

I also added an extra edge loop to the knees to allow for the defamation

02:17

and into the knuckles too.

02:21

Now, there are plenty of other areas that need cleaning up,

02:23

but I didn't really have time.

02:25

So I just focused on the main areas for now,

02:28

I may update the model later on as we work on the different areas of the rig,

02:32

but we'll see how we go.

02:36

So that's the general body topology. And yes, this is a game model.

02:39

So it should be optimized,

02:41

but you should never sacrifice how the model deforms.

02:44

So you can squeeze out a few more polygons.

02:47

Speaking of optimization.

02:49

Another area that needs looking at is this buckle.

02:52

There's far too many polygons here,

02:54

especially for something that isn't seen close up.

02:57

I'm getting distracted though. This won't affect how we come to rig it.

03:01

But it's another thing to keep in mind if you're building a model,

03:05

a good way to judge how many polygons you need to use in a

03:08

model is to see how close that area is going to be on screen.

03:11

If it's never going to be really close to the camera,

03:14

then you don't need lots and lots of polygons.

03:17

So in comparison,

03:19

this area works well because you do need

03:21

those details around the outside of the circle.

03:24

So those extra polygons are needed here.
