Focus Node

T-COMP2-011-006

Use the Focus effect to set up depth-of-field effects for your scene. The Focus node is used to determine how much blur will be applied to images, based on their distance from the focal point.

The focal point can be the zero value of your scene or you can link the Focus node to another node, such as a drawing or peg layer, to retrieve the focal point from the node's Z-axis position.

Refer to the following example to connect this effect:

Use the Focus editor to determine how the focus will change as objects move farther from the focal point.

In the Side view window, you can see how the blur values change based on their distance from the focal point. Select the Focus node in the Node view, make sure you are using the Transform tool, then right-click on the Side view window and select Control from the pop-up menu.

If you edited the function curve and adjusted the velocity, you can also adjust the Bezier handles in the Side view.
