Select 'Bitmap' from the pulldown menu and load the downloaded rust image. Select the 'm' next to the Diffuse color. To do this, download and use the following rust image to create an image map for the material. To add some texture and irregularity to the color of the material, an image map should be used. In this case, just using a color for the material will render too flat and even. However, the de Young facade has a rich, uneven rusting all over the skin that continues to change over time. Rename this material as 'Screen1' so that it can be easily identified later.Ĭolor can be added to a material by simply selecting a color for Diffuse. Right click on Scene Materials and select 'AddVrayMtl.' A new listing should appear. If you are having difficulties with this. If desired, create aĪnd adjust the camera or intensity of the render to make sure the model is clearly visible. To load an existing V-Ray setting (such as the ones handed out in class), click on the V-Ray Options icon. Use the same V-Ray settings that will be used for the final render. Throughout the process of creating a new material, it is important to test-render the actual image to make sure everything is rendering as expected.

Using the material editor dialog, we will edit the transparency, diffuse, and displacement layers to create the pattern of punches across the material, alter the color using an image map, and simulate the bumps of the material. Using the facade of the de Young Museum as an example, this workflow demonstrates how to use custom-generated image maps to define composite material 'layers' in V-Ray.
