The material library is at the core of every BRIKL product. When a material is assigned to a product element, the selected material will share all the colors assigned to it to be customizable in the BRIKL 3D Configurator.
To find where to create materials, look for the Design Tab in the top navigation menu. Then, click on the Material Library Tab. All right, now let's create a new material. Give it an internal ID (Your reference number), a name, and assign colors from your Color Library.
