1. Prepare the Scene
Open 3ds Max. Go to Standard Primitives and create a ground plane with box.
Create a pillar with box.
Create a ball with sphere and put it in front of the pillar.
Turn on Auto Key button.
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
Go to www.scriptspot.com and download Fracture Voronoi script.
Save the script in the 3ds Max Scripts folder.
3. Fracture the Pillar
In 3ds Max, go to Max Script > Run Script.
It opens the Choose Editor file window. Select the Fracture Voronoi script and click on Open.
It opens the Fracture Voronoi script window. Click on Pick Object button and then select the pillar in the viewport.
I have set the Nb parts as 10 since I want the pillar to be broken into ten different chunks.
I have selected the Uniform color option as I want all the chunks in a same color.
Click on Break in 10 button. It breaks the box pillar into 10 pieces.
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
Go to Customize > Show UI > Show Floating Toolbar.
It opens all floating toolbars. Close all toolbars except the MassFx Toobar.
Drag and dock the MassFx Toolbar to the left side of the screen.
Select all pillar chunks and apply MassFx Rigid Body modifier onto them. Select the body type as Dynamic.
Select the ground box and apply MassFx Rigid Body modifier onto it. Select the body type as Static.
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.
Click on MassFx Tools icon. It opens MassFx Tools window. Turn off Use Ground Collisions option.
Now, click on Start Simulation button. You will see the pillar shattering simulation in the viewport.
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.
