In the Materials List, on the Library tab or the Material Editor tab, drag a material onto an object.In the Properties dialog box, on the Materials page under Assign By, click By Object, and then click the Material from the list.On the Edit menu, click the Object Properties command to edit the object.Assign a material through object properties Assign materials by object if you have only a few objects that you do not want on separate layers. Rendering materials are assigned to individual objects and are used by RhinoвЂ™s built-in renderer.ДЄssigning materials by layer is the recommended method. You can assign materials from the material libraries to a layer or object. In the Properties dialog box, on the Material page under Assign By, click By Parent.On the Edit menu, click Object Properties command to edit the object.To assign a material through object properties Then a material can be assigned to the block insert and only the body will adopt that material. But for rendering the body of the car might vary between individual block instances. This way objects within a block instance can adopt the material of the parent block.ДЄs an example, a car model might have tires on the tires layer and wheels on the wheel layer. Objects that are using By Parent assignment will adopt the material of the block insertion. Objects within a Block instance will retain their By Layer or By Object assignments. In the Layer Material dialog box, select the Default Material in the drop-down list.Д«y parent is a seldom used, but useful, assignment.In the Layer Material dialog box, select a material from the Material drop-down list.Select one or more layer names, and click the Material column.In the Materials List, on the Library tab or the Material Editor tab, drag a material on to a layer name in the Layers dialog.Note: Deleting a material from the Material Editor returns all objects that had the deleted material assigned to assignment by layer. To change the material assignment of the layer, use the Layers dialog box. This is the default method of assignment. Assign materials to layersДЄssigning materials by layer assigns a material to all objects on that layer. Editing the material will not affect that material in other models. Once materials are assigned, the material will be saved in the current model. It may take a lot of work to convert the model to By Layer assignments, but it can be beneficial if there is a lot of editing to the render materials planned.

Many imported files will have By Object assignments. Imported files may have any one of these three assignments. Use By object assignment if you have only a few objects that you do not want on separate layers. Using By layer makes it very easy to change the material of all the objects on a layer. Individual objects - Materials can be assigned directly to an object, overwriting any other material assignments.ДЄssigning materials by layer is the recommended method.Objects with a By Parent assignment will look to the block insert for the material. Parent - This is used for objects within blocks.Layers - All objects on the layer will adopt this material, unless they are in a block or have a specific object assignment.The three are a hierarchy, so an assignment lower on the list will overwrite an assignment above. The method used to assign materials has a great effect on how easy the model is to change and maintain in the future. Materials can be assigned in different ways. This is the place where they adopt their rendering material. Objects in the scene have a material source.
