Garbage mask files are created through the Keyer or by the GMask node in Batch. You can import a saved garbage mask setup into Action, and specify 3D properties, such as depth and geometry settings. If your garbage mask is animated, all shapes are imported into Action. Softness and offset settings in the imported garbage mask are not brought into Action. Any holes in the imported garbage mask are also holes in the 3D geometry. For help creating garbage masks, see Drawing a Mask.
TipA library of preset garbage mask setups is available. To load a preset garbage mask, navigate to the /usr/discreet/<product_name>/gmask directory when importing your 3D model.
Once you import a garbage mask as a 3D geometry into Action, use the GMask menu to extrude the garbage mask.
- Depth field
Extrudes the garbage mask, making it three dimensional. Use the depth setting in conjunction with the Axis controls to manipulate the garbage mask.
- Multi Material button
Enable to create an Object Group node for each of the front, back, and extrude of the 3D object. You can then attach a different texture map or Substance to the different parts of the 3D object, using each Object Group node as the attachment point.
- Bevel curve
Adds a bevelled edge to your garbage mask geometry. Use the options in the Edit Mode box to add, select, delete, or move keyframes on the Bevel curve. The Bevel curve behaves in much the same way as an animation curve in the Channel Editor.
- Home button
Resets the Bevel curve viewer to show the whole curve.
- Undo button
Undoes Bevel curve operations.
- Reset button
Click the Geometry and UV Map tabs to apply any of the other geometry settings to your garbage mask.
Click the Tessellation tab to control the tessellation of the garbage mask.
