In this video, you will learn how you can access and use the user defined local library and make it default. You can define your own materials and specify its properties by modifying the properties of an existing material in the list. This user defined material will be available in the material list for a project if it is saved. If you click Save to local library under the material options, your new materials will be saved to the local material library and available anytime you start Discovery. A unique material name must be used to avoid overwriting any existing material.
