Region Checkpoint: Image Comparsion Mask


i tried to specify the image comparsion mask for a region checkpoint, but no mask appears in preview (as you can see on the screenshot - yes i clicked the plus arrow before!). What i´m doing wrong?

  • The image mask starts out including everything in your image.  Use the cursor to define an area on the image.  If you then click on the '+', you will add that area to mask.  '-' will remove it.


    If your mask is all white to begin with, adding to the mask won't change anything.
