You can create and apply basic and free-form geometries to each secondary.

To create a geometry:

1. Enable Geom and then select the shape from the second row.

   
   

2. Use the controls in the centre of the control surface to modify the shape of the geometry, as well as its colour, opacity, and position on the image. You can also apply a blur.

   
   

3. To set softness, use the Geometry Softness dial.

   
   

4. To apply logical operations to the geometry, or invert the geometry, press the More button associated with the second row on the left.
