The Cryptomatte Mask is based on the V-Ray Cryptomatte Render Element.
+/- Pick – Allows you to add/remove items by picking them from the Render View. When activated and the mouse is inside the Render View, a red square indicates where the value is exactly picked.
Value – Sows the mask ID on hover over the rendered frame. If you click on a selection in the Render View, the current ID is added to the list below.
New item – A field to type in a mask ID and add it to the current selection with the + button. The text is case insensitive.
+ – Adds IDs to the list.
- – Removes IDs from the list.

Wildcards are allowed in the New item field. The following wildcard characters are supported:
* – matches any derivatives of the original word (e.g. "Law*" matches "Law", "Laws", or "Lawyer") ? – matches any single character (e.g. "?at" matches "Cat", "cat", "Bat" or "bat") [abc] – matches one character given in the bracket (e.b. "[CB]at" matches "Cat" or "Bat") [a-z] – matches one character from the range given in the bracket (e.g."Letter[0-9]" matches "Letter0", "Letter2")

Each item in the list has a color icon. The color corresponds to the one saved in the respective render element.
Separate items in the list can be changed by double-clicking on them and editing their names.

You can create Exclude items via the -Pick button. This is possible when you have wildcard items and then try to -Pick an item that is not present in the list. For example, we can add all boxes from the scene with a wildcard Box* and then exclude only Box001 with an Exclude item. Exclude items have a minus in their icon so they can be distinguished.

Currently, there are masks based only on some V-Ray render elements. The different mask types filter the list of all elements and show only the suitable ones.
Currently, masks cannot be placed directly on a render element layer. A color correction layer must be placed first on the render element, and then the mask is added on top. For example, a Hue/Saturation layer is applied on the RGB color or a Light Select Render Element layer and then a mask is added on the correction layer so that only the masked area has the correction applied.
