What is the masking tool, and why would you use it?
If you are using an image which the Reveal Studio has indicated will not work with the technology, it is important to be aware that you might be able to improve its compatibility by using the 'masking tool'. The purpose of the masking tool is therefore to strengthen a Trigger Image and thereby improve the launching speed and tracking of an Aura.
The masking tool tells the Reveal viewfinder to ignore anything that it selects, or shades out. This allows the camera to focus on the most successful aspects of the Trigger Image and ensures it is not wasting any processing power on an irrelevant or confusing part of the image.
Note that masking in Reveal Studio will never affect the Trigger Image as it appears in the real world - it is not an aesthetic tool!
Where can I find the masking tool?
There are 2 ways in which you can access the masking tool:
1. Go to Assets > Triggers, select your trigger and double click or hit 'edit' (which will become available in the top right of your screen once the trigger thumbnail has been selected):
2. Start by creating or editing an AR experience - the first step in the process is to upload your trigger. Once it has been uploaded, you can use the masking tool:
How do I use the masking tool?
If you click the button which says 'Mask', you will be offered the option to use any one of three shapes: a rectangle, an ellipse, and a polygon. Using these shapes will create specific zones on top of your Trigger Image which indicate to the Reveal technology that this is an area of the image that should be ignored.
Once you have selected the shape you want to use, simple drag your mouse on top of the image to create the zone. You will notice that a darker shade will take shape wherever you draw the mask - as you can see below:
The Mask Opacity option allows you to make your masks darker or lighter - this is only a visual reference and does not make your mask “stronger” or “weaker” - this can be particularly useful if you have multiple zones you have included on a single Trigger Image. Simply drag the button along left and write to adjust the opacity:
It is always a great idea to test your AR experience after you create it. If you find that it launches slowly, or that the experience is shaky and unstable, try using the Masking tool to help improve performance
You can remove any masking you have applied by selecting the 'delete' option - once the option has been selected, simply click on any zones you want to remove
The polygon tool allows you to be much more accurate with the zone you want to create - in order to finish the shape you create, you need to find the first point you created - once this has been found, the loop will be created
Remember, the masking tool tells the Reveal viewfinder to ignore part of an image, not to focuson it! If you cover an entire image with masking, your AR experience will not launch because Reveal is ignoring the Trigger Image entirely
