Ribbon/Toolbar Icon Command Command Description

Set Pdi Dynamic Properties

This window includes all the dynamics properties of the objects as single rigid bodies. It is disabled for objects that belong to a fracture body (fragments).

Create Pdi Body

In this window users are able to set the collision shapes and type of the objects as single rigid bodies. It is disabled for objects that belong to a fracture body( fragments).

Shatter It Feature

Shatter It! is the pre-cutting tool of Pulldownit, in this window users can define the shatter pattern, number of fragments and other options. You can shatter any polygonal mesh, convex, concave or with holes. Although Shatter It can be used independently of the rest of the plug-in, its mayor advantages come when computing dynamics for the prefractured object with the Pulldownit solver.

PDi Advanced Fractures

This window allows users to have more control in the way objects fracture, you can define the location and start frame of the cracks as long as the break threshold of selected areas in the object, also modify the fracture body by detaching parts of it.

Add jagginess to fragments

In this window you can add jagginess to fragments to get a less polygonal look and rough faces. You can add jagginess to fragments generated with Shatter it! Tool before or after computing dynamics, however to get better simulation performance adding it after baking keys is recommended.

Create Pdi Crackers

In this window you can setup cracker objects intended for creating long dynamics cracks over surfaces, you count with several parameters to adjust the cracks behavior.

Pdi Solver Options

In this window users are able to set the global parameters for the Pdi scene in both dynamics and performance.

Bake Pdi Simulation

In this window users can bake dynamics to animation keys; also some utilities regarding system resources are present.

Manage Pdi world

In this pop up window users are able to add or remove rigid bodies from simulation, also delete all the PDI entities to clean the scene or start again from scratch if needed.

PDi Basic Fractures

In this window user can create Fracture Bodies selecting geometry in scene; also set the global parameters of the fracture bodies.


The installer that ran when you downloaded this plug-in from Autodesk App Store has already installed the plug-in.

Windows only: To uninstall this plug-in, simply rerun the installer by downloading it again from Autodesk App Store, and select the 'Uninstall' button, or you can uninstall it from 'Control Panel\Programs\Programs and Features' (Windows 7/8/8.1/10) or Add/Remove Programs, just as you would uninstall any other application from your system. The panel on the Plug-ins tab will not be removed until Maya is restarted.
