The original source object is replaced with the new object.
The HUD displays a selected replicator’s most essential parameters. Blend Mode,
Opacity, and Shape always appear in the HUD.
When a replicator and the Adjust 3D Transform tool (in the Toolbar) are selected, the 3D
transform tools become available in the HUD. These additional controls allow you to
transform the replicator in X, Y, and Z space, regardless of whether the group is 2D or
3D.
For more information on using the 3D transform controls in the HUD, see “ 3D
Compositing ” in the Motion Supplemental Documentation PDF.
