On this page

Overview

This tool will blend the transform of the current parent with other objects and apply the current local object local transform on top.

Using Parent Blend Constraint

  1. Click the Parent Blend tool on the Constraints tab.

  2. Choose the object you want to constrain and press Enter to confirm your selection.

  3. Select one or more parents objects in the desired order. Hold ⇧ Shift to select multiple objects.

  4. Review the Toolbar Parameters. Some of the toolbar parameters match node parameters directly (such as Mask and Weight), while other (such as Mode, Keep Position, and Add Keyframe) affect how the nodes are created.

  5. Press Enter to confirm your selection.

This tool creates a new constraints CHOP Network inside the object, or reuses an existing one.

A Parent node is added along with one Simple Blend node based on the new parent objects and blend mode. The constraint is added after the node that has the output flag and the output flag is moved to the new node.
