Switching 3D Composites to 2D Composites

In part, 2D rendering is faster because most of the 3D settings are simply ignored. This explains why 2D and 3D composites can exist within the same workspace.

When you switch an existing 3D composite to 2D mode, there are a few implications with respect to how the controls may already be set. Most of the settings are ignored, though. Here are a few examples of what is ignored:

• Lights are ignored in 2D, so the settings for shading, shadows, and reflections made in 3D will not affect the 2D result.
• Layer controls
• Extra transforms such as X and Y Rotation
• Four-Corner Shape
• Hinge and Target are ignored; the layers snap back to their original positions and rotation values.

Note the following changes that may affect the result:

• You can use parenting in 2D mode; all layers are restricted to 2D transforms.
• You can also use the Align options, but only with X and Y alignment. The Align Z button becomes unavailable in 2D mode.
• You cannot target in 2D mode; the Target list becomes unavailable.

To switch a composite from 3D to 2D:

1. Select the composite in the Workspace panel, or double-click the composite node in the Schematic view.

The Composite Controls panel appears.

2. Click Output to show the Output controls.



3. Enable the 2D Mode button.

The panels for the other controls are adjusted for the selected compositing mode. See Comparing 3D and 2D Options for a list of changes.
