Chapter4:ZBrush - Displacing Stones and Sculpting Snow

In this chapter we will use our hand painted displacement maps to displace stones onto our well within ZBrush. Then I will demonstrate a technique for laying snow onto our stones using an old but powerful trick.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

We add a displacement map:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Change the instensity:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Then we apply this displacement:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Turn off the texture map:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

But we find we do not have enough tessellation:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

So let's undo that displacement, and subdivide this up until about a million or so.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Then do this one more time:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

One thing that should be mention is that the 0.5 means that there's gonna be no displacement, means the gray place in that displacement map:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Apply this displacement:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

If change to one:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

If change to zero, then also be another result. So we should keep that 0.5 to get the result which can match the displacement map:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

One thing we notice is that there's obviously some funky stuff happening up here that's where we have the uv scenes where they connected. We will smooth that out a bit. And it also will be covered by snow so we don't too worry about that.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Turn off this displacement map:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Smooth these funky stuff:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

We can also use trim dynamic brush:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Repair these place till you get most of this kind of taken care of .

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Well done:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Turn on the texture map and we find it's very nice:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

The next thing we gonna do is make a snow match this

First, we make a duplicate:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

The bottom one will be the snow object and the top one will be the wall object.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

What we gonna do is we're gonna apply different materials to each of these. So we activate the materials and then we can flood these with different colors.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

We give this, which kind feel like snow.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Fill object:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Original object, give it gray and fill object:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

So we have snow underneath and this one on the top, choose the first one

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Keep this texture map on:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Chose the second one:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

In order to put those different materials on you have to turn this on first material channel. Now we turn off it because we don't need it anymore.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Now we need to offset the snow. We got the transform tool to drag that out. Move it up. holding down the shift key.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Then we got snow sitting on the top of the stone.

We go back to the stone base that we had here, turn off the texture map.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Create the plane

Then we should create a plane.

We need to do is go to another subtool over here.

Just click sth like cylinder:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Click that again, to find plane:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Go to snow subtool and add this plane:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Rotate it:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Scale this up:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Show everything:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Next we go to push and pulling the snow plane around a little bit.

Subdivide it once:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Use this dots to create some more organic and lumpy.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

And invert the edges:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Corners we can use move tool to pull down a bit all around the edges.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Mask:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Ctrl+w and shift+f

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Then ctrl+shift+click the middle one:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Then delete lower and delete hidden:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

The UVW seam is on the other, so we will make the snowdrift on this side:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Sometimes you're trying to work this you'll see that the sides are still moving and not building up right around here that's because when these subtools are active and not in transparency mode, it acts like a kind of blocker which is actually quite useful.

But if you come down here and click this:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Now we can sculpt under here:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

We can build our snowdrift along the side of the well.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Subdivide:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Turn the material channel then give this plane a white material:

Fill object:

Sculpt the snow on the rock

Let's give our snow on the rock a little bit of love.

We want to be able to blend and even a little bit nicer between here, and also we don't want such a uniform distribution of snow along all the rocks.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Reference: actual snow on the top of the rock. Have so many break ups.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Click the snow subtool over here:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

To repair these place to make sure that there's no empty rock space.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Where the wind is gonna be blowing heavier we're gonna have thicker amount of snow….just follow your imagination who knows.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

We actually have a little bit more building out from here so it feel like it's mounting up.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

To make a beautiful blend:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Press alt key to delete some snow:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

We want make some break up so we find an alpha which have a little bit break up:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Make it a little bit more barren:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Some place can use clay build up to add something:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Smooth these place:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

When done, let's add a little bit of this kind of texture to the plane

We can do the same thing let that brush that we had but which probably shouldn't make it too big because we want to keep the same frequency

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Use alpha to make noise

Something like this can take a lit bit too long so another we can do too is since this technically has UV maps on it we can make an alpha map to do something really quickly.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Import an alpha map: even though this is moss I think it will make an interesting mask for this.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Let's go to mask and click that:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

However, I want to get some high frequency so we're gonna do some tiling on this

Let's change these two to three:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Then mask by alpha again:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Five five:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Now if we sculpt on here and I'm going to turn off the alpha, turn back to the default brush, you can see we're just painting on and it's getting the shape.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

If we press ctrl H you can hide the mask and it's still technically active:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

And the other thing we can do too is if we want quickly get some deformation or interesting stuff in here. Ctrl H to show the mask again and we could come down here to deformation and we can play some like inflate let's dress like 10:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

There's an interesting noise appear。

Ctrl H hide the mask:

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Turn this tiles back down because if I use an alpha again later that'll active here too even if I'm on a brush.

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™
3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

Let's smooth some of these areas out on our snow plane. We just don't want this to feel too uniform and CG

3D Sculpting with Photos(stone and snow)-Part4-魔法森林™

We could take this in key shot right now.

But we also can use standard brush to make some deep hole or sth others just to have some imperfections you know.
