I have been using lens studio for a while and have gotten quite familiar with it. My next lens requires me to create a sort of mask effect. For example I need a circle in the middle of the screen that shows what the camera sees and feathers out to the edge so underneath a copy of the camera layer I can place an animated background of sorts.
Now of course I could just export the animated background with this feathered circle already cut out and place it over the camera image for the same affect, however this would take up too much space as every frame of the animation would have to be a PNG with that feathered circle cut out in the middle.
Does anyone know how to achieve a mask like effect?
