When you move vertices, the tangent handles of the two adjacent vertices remain fixed in their current position. You can make them automatically adjust to create smooth curves between the vertices by pressing the G hotkey as you move vertices.

You can reverse the behaviour so that dragging vertices automatically adjusts tangents without using the hotkey. You reverse the behaviour by setting the following environment variable:

DL_GMASK_AUTO_MOVE_MODE

To reverse functionality of the G hotkey:

1. From the home directory of the application, open the .cshrc file in a text editor:

2. Add the following line to the end of the .cshrc file:

   setenv DL_GMASK_AUTO_MOVE_MODE

3. Save and close the .cshrc file.
4. In the home directory, type:

   source .cshrc

5. Launch or restart the application.

   When you click or move a vertex on a garbage mask, the tangents are automatically repositioned. When you press G and click or move a vertex, the tangents are not repositioned.

   TipAlternatively, you can set the environment variable in the shell pointing to the home directory of the application. When you set an environment variable in the shell, the environment variable is enabled for the current session only.
