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

If Geo Channels are used, one Geo Channel per Mask will be created.

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.

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

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