Overview

This tool is useful for constraining a constrained object to another. For example, you can constrain two things rolling down a hill together.

You need to create a constrained RBD object before you can use this tool.

Note

This constraint will not work with packed primitives. However, you can achieve the equivalent using a constraint network.

Using Parent Constraints

  1. Click the Parent Constraint tool on the Rigid Bodies or Animation tab.

  2. Select the constraint to change parent and press Enter to confirm your selection.

  3. Select the new goal object and press Enter to confirm your selection.

Moving a Parent Constraint
