Increasing material samples will increase render time, but the increase is specific to that material. Material Samples 32 and up: Generally unnecessary Material Samples 17-32: Cloudy plastics, dielectric, translucent materials Material Samples 13-16: Finely textured materials, satin finishes Material Samples 9-12: Good for most basic, opaque materials

Material Samples 2-8: Sandpaper, cast iron, rough plastics Some suggestions for the number of material samples: All of these existing materials are extremely powerful. Inversely, you can decrease the material samples to give them an extremely rough appearance. There are 700+ materials within 13 different categories for KeyShot 3. All other material and render settings are the same.įor most materials that have either some roughness, internal roughness (smoky, frosted, or translucent materials), or a bump texture, increasing the material samples will give a more refined material appearance. In the image below, the only difference between each image is the material sample value for each. If you're not happy with the material quality, you can increase the material samples instead of increasing the output render settings. In most other materials the Samples slider will already be visible. In the image below you can see the Paint material type has Samples control and it's in the same place for other material types: Glass (Solid), Metal, Plastic (Transparent), Gem, Velvet, Dielectric, and Ground. Most materials allow us to increase the sample value, and this parameter is often found in the drop-down next to Roughness. This is especially important when adding roughness or bump textures to your materials.

With this variety of parameters, materials such as metals, plastics, transparent or cloudy plastics, glass, leathers and diffuse materials can all be created from this single material type. There are more parameters in this material than in any other. Most materials in the KeyShot library include a default sample value for that material, but you can increase this value in order to get better quality materials in your renderings. KeyShot Advanced The Advanced material is the most versatile of all KeyShot material types. Material Samples (sometimes called glossy samples) control the amount of information a material collects from neighboring objects or the surrounding environment.
