Connecting a Snapping Source Drawing to an Animated Matte Generator
T-COMP2-002-013
In order to make the contours of an Animated Matte Generator to a drawing in your scene, you must first connect that drawing to the Animated Matte Generator node through its Snapping Source (left) port.
NOTE The Snapping Source drawing of an Animated Matte Generator must be a single vector drawing node. Snapping will not work with any other type of node.

- In the Node view, create a connection going from the output port of the snapping source drawing node to the Snapping Source (left) input port of the Animated Matte Generator node.
- Create a connection going from the output port of the snapping source drawing node to the input port of the source drawing node. This will ensure that if the snapping source is moved or animated, the matte will follow the movement of the snapping source.
