1. Prepare the Scene

Step 1

Open 3ds Max. Go to Standard Primitives and create a ground plane with box.

Step 2

Create a pillar with box.

Step 3

Create a ball with sphere and put it in front of the pillar.

Step 5

Go to the tenth frame and drag the ball through the pillar. It will create an animation of the ball passing through the pillar.

2. Installing Fracture Voronoi Script

Step 1

 Go to www.scriptspot.com and download Fracture Voronoi script.

Step 2

Save the script in the 3ds Max Scripts folder.

3. Fracture the Pillar

Step 1

In 3ds Max, go to Max Script > Run Script.

run script

Step 2

It opens the Choose Editor file window. Select the Fracture Voronoi script and click on Open.

Step 3

 It opens the Fracture Voronoi script window. Click on Pick Object button and then select the pillar in the viewport.

Step 4

I have set the Nb parts as 10 since I want the pillar to be broken into ten different chunks.

Step 5

I have selected the Uniform color option as I want all the chunks in a same color.

Step 6

Click on Break in 10 button. It breaks the box pillar into 10 pieces.

Step 7

You can further break each broken piece into several more chunks. Select a broken piece and then repeat the process from Step 1 to 6.

4. Fracture Simulation

Step 1

Go to Customize > Show UI > Show Floating Toolbar.

Step 2

It opens all floating toolbars. Close all toolbars except the MassFx Toobar.

Step 3

Drag and dock the MassFx Toolbar to the left side of the screen.

Step 4

Select all pillar chunks and apply MassFx Rigid Body modifier onto them. Select the body type as Dynamic.

Step 5

Select the ground box and apply MassFx Rigid Body modifier onto it. Select the body type as Static.

Step 6

Select the ball and apply MassFx Rigid Body modifier onto it. Select the body type as Kinematic. Turn on Until Frame option and give it a value as 5. It means that the ball will act as a kinematic object till five frames and after that it will become a dynamic object.

Step 7

Click on MassFx Tools icon. It opens MassFx Tools window. Turn off Use Ground Collisions option.

Step 8

Now, click on Start Simulation button. You will see the pillar shattering simulation in the viewport.

Conclusion

MassFx is a great dynamics tool in 3ds Max. It is quite superior than its predecessor Reactor. Hope you have enjoyed this tutorial. I will cover other aspects in forthcoming tutorials.
