Materials |
The Materials command opens the Materials panel which specifies the color, finish, transparency, texture, and bump for use by the built-in Rhino renderer.
Materials can be dragged and dropped onto any Material, Texture, and Environment control.
Colors can be dragged from a color swatch and dropped onto a different color swatch.
Drag a texture from a texture field and drop it onto a different texture field to move. Hold the Ctrl key to copy.
Material Editor displays materials used by objects in linked 3dm files. The materials can be used in the current model, but they are not editable. Double-click a linked block to edit the materials in a new Rhino window.
Material preview thumbnails are rendered by the selected render device in Options > Cycles.
When assigning a material to a block instance, you will be prompted a question. The material will be assigned differently depending on how you answer the question.
Yes assigns the material to all objects in the block instance.
No assigns the material to the block instance. Objects in the block instance need to set Use Object Parent to inherit the block instance's material.
Render contents (materials, environment, and textures) can be hidden by plug-ins or scripts. More information...

Textures (images or procedural textures) can be used for color, transparency, bump, and environment.
Rhino supports the following file formats:
Transparency is not supported in these formats:
Transparency is supported in these formats:
Click (click to assign texture) to assign a texture.
When a texture has been assigned to a setting:
Specifies a texture to use as the material's color.
Uses a texture to control the material's transparency.
Uses a texture to control the material's bump depth or object's normal direction.
Bump and Normal maps add details to surfaces in rendering without modifying the shape of the surface.
Uses grayscale values of a texture to make a surface appear bumpy.
Uses RGB values of a bitmap image to alter surface normal directions.
Uses a texture as the material's environment reflection.
The image should be an angular map or light probe projection (spherical) image. Other image projections will produce the reflection effect, but it will be distorted and not produce the realistic environment reflection.
Advanced Settings
Allows the material to render the diffuse color with shadowing and shading by enabling diffuse lighting.
If this setting is on, the object renders with shadowing and shading.
If this setting is off, the object will render the diffuse color all over with no shadowing or shading. Turning this setting off ensures that the color the texture of picture frames remains constant over the surface.
Causes objects to reflect fully at glancing angles and only slightly reflect when the object is seen head on.
This effect simulates many transparent or semi-transparent materials, such as glass, plastic, and materials that have a thin transparent glaze, such as laminated paper, polished woods, and paint.
Allows images with an alpha channel for transparency to make the object transparent in the areas of the image where the alpha channel is applied.
Makes the surface reflections fuzzy. For surfaces that are perfectly reflective, such as mirrors and chrome, use 100% polish. Lower values model materials like certain plastics and the sanded surface of frosted glass.
Changing this setting can increase rendering time.
Controls the clarity of the material.
Creates translucent materials like tracing paper or hand-made glass.
Changing this setting can increase rendering time.
Creates clear materials such as water, float glass, and diamonds.
Adds a color to the shaded result. It does not take into account the lighting, so if the emission color is white, the object will always appear white. If the emission color is gray, all parts of the object will appear brighter than they would otherwise.
Double SidedThe Double Sided material allows to display different materials on the front and back sides of a "thin" object that does not have a physical thickness, such as a single surface or mesh.
Double Sided Material

Physically BasedPhysically Based Rendering (PBR) simulates interaction between lights and surfaces in the real world to create photorealistic renderings. Different material types usually use different shading methods. The physically based material type integrates several shading methods into a single material.
Physically Based Material
The diffuse color of the material that displays when no texture is assigned.
Click the color swatch to select a color from the Select Color dialog.
Controls the smoothness of object surface. Rough surfaces reflect light rays in a wider range of angles that make reflection blurry.
Move the slider to change the value.
Double-click the slider to enter a number.

Detailed settings
Click Details settings to enable/disable shading methods.
When any setting has (click to assign texture), the setting can be controlled by the assigned texture.
Base Color / Metallic / Roughness
The diffuse color of the material that displays when no texture is assigned.
Click the color swatch to select a color from the Select Color dialog.
Controls transparency of the object with the bitmap texture's alpha channel.
Gives the material a metal appearance. Details...
Controls the smoothness of the material. Details...
The bitmap image for metallic texture can be used as the roughness texture, but the colors have to be inverted to add roughness to the rusted portion instead of the non-rusted portion.
Subsurface parameters control how light rays penetrate the surface of a translucent object and scatter inside the object.
Scattering Radius is based on model units.
The specularity parameters scale the reflection highlight on non-metal objects.
Scales the brightness of reflection highlight.
The amount that the specularity is tinted by the base color.
Anisotropy parameters control the aspect ratio and orientation of the specular highlight to simulate directional brushed metal materials.
Changes the aspect ratio of the specular highlight.
Changes the angle of the specular highlight. The value can be 0 (0°) to 1.0 (360°).
Sheen parameters mimic the rim specular effect usually seen on some fabrics like silk.
Increasing Roughness blurs the rim specular.
Controls the width of the rim specular.
The amount that the rim specular is tinted by the base color.
Clearcoat parameters simulates the highly reflective layer on top of the base paint of a car.
Controls the reflection intensity of the clear coat.
Bump uses grayscale values of a texture to make a surface appear bumpy. Normal uses RGB values of a texture to alter surface normals.
Controls the roughness of the clear coat.
The roughness of the base paint is controlled by the base roughness setting.
Opacity parameters control the transparency of the material.
Changes the transparent level of the object.
Sets the index of refraction.
Controls the roughness of refraction.
Changes visibility of the object. Reducing the alpha value also reduces refraction effect.
When the value is set to 0, the object will be completely invisible.
Emission parameters turns an object into a light source.
The lighting color.
Increases or decreases the lighting intensity.
The material will be rendered with the base color when Multiplier is set to 0.
Bump / Normal and displacement
Bump / Normal and displacement parameters use textures to add details to the surface of an object.
A bump map uses grayscale values of a texture to make a surface appear bumpy.
A normal map uses RGB values of a bitmap image to alter surface normal directions.
Two flat cylinders (right) using a metallic material with/without the normal map (left).
Displacement uses grayscale values of a texture to move an object's render mesh vertices.
Displacement is based on model units.
Ambient Occlusion parameters use a bitmap image to add fake shadows of ambient light to the object.
An ambient occlusion map is a bitmap image baked from a 3D model in a rendering to store the indirect lighting information of ambient light when the model is rendered.
PictureThe name of the material.
The Picture contains a simple bitmap image.
The path and name of the bitmap file.
See also Bitmap Texture.
The Self-Illuminated option causes the image to always display at full intensity and is not affected by light or shadow.
The Grayscale option sets the image color to 256-grey
Specifies transparency settings for the image. Specify a transparent color to be used as an alpha channel in the case that no alpha channel is specified in the image.
