Extrem samples of this materials are looking flat, sometimes like textured emitters without self shadowing. All this materials seems to show a light distribution particular independent from the direction of the light. Typical examples of rough surfaces are the moon, felt, cloth, clay. Rough material Often used for Rough materials is a special render model based on the theory of Oren-Nayar. l Rubber material: of 38TutorialM < VfR < TWiki Rubber show very blurry speculars and so it is better to use the shiny plastic material with blurry reflections. l Wood material (reflection intensity boosted by double reflection layers - see 'Tricks' at the end) : Rubber material The standard diffuse material looks dull, but for Rubber it should not be used. l Wood material options: of 38TutorialM < VfR < TWiki Take a texture at the diffuse layer, set reflection at fresnel and set a reflection glossiness like necessary - 1 for clear finish or less for waxed wood. Sounds strange, but anything are bits and bytes only in the CG world. Wood material Wood is a kind of textured plastic material. * Fresnel control of the reflective layer: l Shiny plastic material: of 38TutorialM < VfR < TWiki A basic rule for shiny plastic is, that the reflections are not tinted by the material color. The refraction parameter can be ignored here, it is a current interface issue. The IOR is a material specific parameter and can be find for example at this list here (link wanted). If we add a reflection layer and set the reflection map type to 'fresnel', than we get shiny material like shiny plastic or Ceramic. l Single diffuse layer material: Shiny plastic or Ceramic material of 38TutorialM < VfR < TWiki Textures are using the map channels of the McNeel ? mapping tool (RCM). The edito will open per mouse click on the little 'm'. The color can be set per Rhino color chooser or texture editor. It looks like loot (Plasticine) or a dull plastic. Diffuse material Simple to create and fast to calculate - the diffuse material. l Extra controls of the preview window: r18 - 11:55:19 - MichaelMehnert of 38TutorialM < VfR < TWiki l Screenshot of the VfR material editor: If the user like to see the difference between two material settings per preview, than the prepass of the preview window should be disabled per RMB at the preview window.

All example renderings are done in full adaptive mode and noisethreshold 0.02 (good preview quality). The preview window dosn't show the current selected material, it show the last rendered preview. Additional layers can be placed per RMB click on a layer type. The default material contain one acitve diffuse layer. All layers are in order like placed on the material from top to down. A layer type can contain unlimited layers.

A material can based on four layer types - emissive, reflection, diffuse and refraction.

Per right mouse button (RMB) click on the 'Scene Materials' materials can be imported, added new or purged unused materials. TWiki > VfR Web > UserTutorials > TutorialM Materials Introduction The material editor can be open per Rhino3D menu 'Vray' -> 'Material Editor'.
