Chapter3:Creating a stone well base mesh with uvws

In our first ZBrush chapter we will create the base mesh of a stone well using some standard ZBrush techniques. We will also learn how to create Boolean objects to cut holes into our Subtools, followed by how to create and edit UVW maps with the "UV Master" Zplugin Tool.

First. Building a new document:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

We can change the background color in this place to let us feel comfortable:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Grab a cylinder, this is going to become our well eventually. Then press T.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Then make polymesh 3D so now this is an actual active object that we can work with.

We should subdivide it but if we do not turn off the default, the edges will be very smooth:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

But we want to keep that a little bit tighter so we should turn off the default smooth one and divide again:

Then we turn on the Smt again and divide, then the angle will not be that smooth:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Then we delete lower before we dynamesh

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

So we come down here to DynaMesh, Let's click this just with the default settings.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Shift F, this had a point in the center which doesn't give us some nice to pology(拓扑) through here. So that's why we are going to dynamesh that. We dynamesh.

The next thing we are going to do is we're going to duplicate this mesh down and this is going become our cutter object that bottom one. (do Boolean)

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

We should click this one, this will make the bottom one a cutter object

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Then we find [polygroups], and we see this

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

And that's going to allow this to be able to subtract once we get ready to cut and merge. But first we what to do is change the scale of our object.

Press W to go to our move tool

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

W/e/r is our common shortcut keys:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Clicking here to drag, hold down the shift key, it's going to lock this to the axis and snap to an orthographic view which is extremely helpful to precision maneuvers.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

The next thing we are going to do is let's scale this down a little bit.

Press E to scale mode.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Hold down shift to move

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Then chose the top objects

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Click the merge down:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

And once we merge down now:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Then hold down ctrl
then click and drag on the side here

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Before we lay out our UVs which is our next step one thing that I like to do is anything that we're not going to be able to see, I like to delete it.

This is our final images, so the bottom of this pipe we're not going to need to see any topology.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

So let's go ahead to make a new mass group by pressing ctrl and dragging this on the bottom.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

And with that mask activated we're going to press W then we have a new sub group down here and we're going to delete it out.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Ctrl+shift and click this.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Then we need to get out of the move tool so we press B to get a standard tool

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Clear our mask:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Ctrl+shift click:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

And click it again:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Turn out this dynamesh so it's not active anymore

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

And go to modify topology to delete hidden:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Then press X and press shift to paint these place, so we can smooth that out. When done, we press X again to turn off symmetry.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Then we will make uvw maps

So we go to the z-plugins and drag it over here to the side

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Expand uv master, but I want to activate polygroups and that's gonna allow me to separate uv islands based on the poly groups that we have:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Right now we create two: one for the interior and one for the exterior

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

However we're not gonna get a good relax on the exterior cylinder if we still have the top part connected so we should make another polygroup.

We're gonna once again pull down the ctrl key drag out a mask.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Then ctrl+w that's just a hot key for making a new mask and even though it's the same color it technically is a different poly group.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

You can double-check that by doing ctrl shift clicking and indeed we do have three different poly groups.

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

So now let's go ahead and use the unwrap tool but polygroups active and just hit unwrap:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

It will take some minutes and we can see on the top:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Let's go to flatten:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

This is a little bit crooked.and it's not the best use of all our UV space. Ctrl shift click this one and that'll isolate just this guy then we gonna press W to go to the move mode, just go to the transform tool let's drag that out and let's go to R and we're gonna rotate this a bit

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Ctrl shift click this and move it:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Ctrl shift click this one and move this guy down too:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Rotate it nicely:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

When we done it, we unflatten this:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Then let's press shift F

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Go to the texture map and click this then import:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Find diffuse and open:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

But the stuff looked a little bit stretched well. So what we can do is flatten this out again and change it to what we have before. Then stretched it to test

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™
3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Let's see what happened:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

So it's wrong. Then what we should do is stretch it the other way:

3D Sculpting with Photos(stone and snow)-Part3-魔法森林™

Now we have sth looking pretty good.
