In this part of the tutorial series, I'll show you how to create a wall fracture scene using PullDownIt in Maya.
1. Creating Pdi Bodies
Step 1
Open Maya.

Step 2
Go to Create >
Polygon Primitives > Cube and create a cube in the perspective view
port.

Step 3
With the cube selected,
go to PullDownIt menu bar and click on the ShatterIt feature
icon.

Step 4
In the ShatterIt
feature window, set the values of Shatter Style to Wood Splinters,
Num Centers to 150, Main Axis to L(longest) and then click
on Shatter It! button. You'll see the cube gets shattered as shown in
the following image.

Step 5
Select the indicated
upper and lower chunks of the mesh and create a new layer. Rename the layer as StaticChunks.

Step 6
Turn off the visibility
of StaticChunks layer. With the rest chunks selected, create a new
layer. Rename the layer as DynamicChunks.

Step 7
Go to StaticChunks layer.
With the static chunks selected, click on Create Pdi Body icon.

Step 8
In the Create Rigid
Body window, select the Type as Static and then click on Mesh
option.

Step 9
Go to DynamicChunks layer.
With the dynamic chunks selected, click on Create Pdi Body icon.

Step 10
In the Create Rigid
Body window, select the Type as Dynamic and then click on Mesh
option.

2. Creating Pdi Fracture
Step 1
Create a ball in the
perspective viewport.

Step 2
With the ball selected,
click on Create Pdi Body icon. In the Create Rigid Body window,
select the Type as Dynamic and then click on Mesh option.

Step 3
With the ball selected,
click on Pdi Dynamics Properties icon. In the Pdi Dynamics Properties
window, set the Initial Velocity X value to -50.

Step 4
Press the Play
button to see the simulation. The ball hits the wall and the dynamic chunks
shatter into pieces.

Step 5
With the dynamic chunks
selected, click on Pdi Basic Fractures icon.

Step 6
In the Pdi Basic
Fractures window, click on Create button. It opens Set up
Fracture Body sub- window. Here set the name as Wood and then click
on Accept button.

Step 7
Increase the value of Clusterize(%)
to 100 to get more detailed fracture.

3. Creating Front Wall Fracture
Step 1
Create another wall of the same dimension and keep it at the front.

Step 2
With the front wall
selected, go to PullDownIt menu bar and click on the ShatterIt
feature icon.

Step 3
In the ShatterIt feature window, set the values of Shatter Style to Uniform, Num Centers to 120 and then click on Shatter It! button.
You'll
see the wall gets shattered as shown in the following image.

Step 4
Select the indicated
chunks of the front wall and create a new layer. Rename the layer as WallStaticChunks.

Step 5
Turn off the visibility
of WallStaticChunks layer. With the rest chunks selected, create a new
layer. Rename the layer as WallDynamicChunks.

Step 6
Go to WallStaticChunks
layer. With the static chunks selected, click on Create Pdi Body
icon.

Step 7
In the Create Rigid Body window, select the Type as Static and then click on Mesh option.

Step 8
Go to WallDynamicChunks
layer. With the dynamic chunks selected, click on Create Pdi Body
icon.

Step 9
In the Create Rigid Body window, select the Type as Dynamic and then click on Mesh option.

Step 10
Create another wall at
back. Keep it static.

Step 11
Hit the Play
button to see the simulation. The ball hits the wall and the dynamic chunks
shatter into pieces.
