There are two ways to duplicate a rigid body. One way is to use the copy, cut, and paste command combination, while the other is to use Duplicate Special.
When you use copy, cut, and paste, the original and duplicate rigid bodies share the existing solver.
When you use
Duplicate Special, the solver is
duplicated along with the rigid body.
Note: Using Duplicate Special with Duplicate Input Graph is very inefficient. This process duplicates everything attached to your rigid body, which means that you get duplicated solvers and passive colliders for every rigid body and your setup is no longer connected to one solver.
To use the Duplicate Special method of copying a rigid body, do the following:
- Select the rigid body and its associated constraints in the scene.
- Select Edit > Duplicate Special. The Duplicate Special Options window appears.
- In the Duplicate Special Options window, activate Duplicate Input Graph. (See the note above about the limitations of the Duplicate Input Graph method.
- Click Duplicate Special.
