The Vizrt 4 Soft Mask Shader will allow you to create a soft edged mask along one side of your container. You can also flip the position or adjust the angle of the soft mask to affect a different edge.
The Soft Mask is found in the Built-Ins Window, the Shader tab and the Effect folder. It is one way to create a mask within Vizrt. The advantage to using this one is that you can soften the edge. The disadvantage is that it only affects one side at a time.
