Material ID Channel from Selection Groups allows you to create a a new channel with a unique

color fill for each selected selection groups. All selection group types (object, patch, faces) are supported

Material ID Channels are a useful way to have a single channel for multiple material masks.

Optionally the tool allows you to create individual mask layers from each selection group.

Currently there are two ways to utilize Material IDs in Mari

• create a 'Color to mask' Adjustment Layer and pick the ID Color
• use the Extension Pack Material Regions with their built in support for Material IDs

Filtering options at the top of the dialog allow you do search through the list of Selection Groups.

• Deactivate the filter by clicking on the Magnifying Glass

• Search for multiple words by separating them with a comma (,)

• Search in Case Sensitive or Insensitive Mode by clicking on the Aa / aa Icon

• Search for matching or non matching words

ID Overrides allow the user to specify a custom ID Color for the selected Selection Groups on the right hand side list of the dialog.

The Functionality is also available via the right mouse click menu in the Selection Group Palette.

• Set ID Color Override

Let's the user choose a color for the selected Selection Groups that will be used as their ID Color.

• Clear ID Color Override

Removes a user chosen Color from the selected Selection Groups and returns them to a random color unless

Use Previous ID Color option is on

• Channel

The name of the channel to create as 'Material ID' Channel.

If the name already exists, selected selection group IDs will be added to the existing one

• Channel Resolution

The resolution of the 'Material ID' Channel to create if the Name entered does not exist already

• Generate ID as

• ID Color

Will create a colored ID layer in the specified Channel

• Mask

Will create one black/white mask layer per Selection Group in the specified Channel

• Use previous ID when available

If a Selection Group has been baked previously, this will automatically reuse the previously baked color as ID Color on the new bake.

This is useful in case a selection group has been updated with new faces to quickly apply the previous color to the new faces.

If a Selection Group has previous Color Information, the Selection Group Name will be highlighted in the color that will be used for baking.

• Use ID Color Override

With this Option turned on, Baking ID Maps will respect custom ID Colors selected by the user

Overrides can be set via the Overrides Buttons or the Selection Group Right Mouse Click Menu
