# Inverting a Matte

Use the Negative node to invert a matte. By inserting the Negative node between the Matte Edge and the GMask nodes in the processing pipeline, the matte is automatically inverted. The Negative node has no settings to configure.

To invert a matte:

1. From the Modular Keyer Node bin, drag the Negative node to the schematic.
2. Hold Shift and drag the Negative node to the Matte Edge node so their tabs touch and repeat for the GMask node.

   The Negative node is inserted to the schematic and your matte is inverted.
