Multi Material

The MultiID operator lets you assign different materials on a single mesh. This works by associating mesh faces to different “IDs” or “groups”. You can set up your model’s MultiID values in another software or add a Material IDs operator in the model asset.

To use this feature apply a material with a MultiID operator to a model that has been setup with material id values. Then the corresponding Material ID Asset of the MultiID operator is applied to the model asset.

Default Color	Defines the default color when no material asset is assigned to the Material ID group. We use a color picker that can use RGB, HSV or HEX inputs.
Material ID 0 - Material ID 29	This is where a user applies which material asset is applied to the corresponding Material ID number. You need a model asset with Material IDs in order for this to work correctly.
Is MultiID	MultiID when checked enables having multiple materials on a single mesh.

Avoid using MultiID Materials, as they can have a serious impact on performance depending on the mesh density
