Note that intermediate values between 0.0 and 1.0 do not correspond to any physical material. Metalness – Controls the reflection model of the material from dielectric (metalness 0.0) to metallic (metalness 1.0). For more information, see the Fresnel Option example below.
Normally this is locked to the Refraction IOR parameter, but it can be unlocked for finer control. This parameter can be mapped with a texture in the Maps rollout. Note that the Fresnel effect depends on the index of refraction as well.įresnel IOR – Specifies the IOR to use when calculating Fresnel reflections. Some materials in nature (glass, etc.) reflect light in this manner. For more information, see the Reflection Glossiness example below.įresnel reflections – When enabled, the reflection strength becomes dependent on the viewing angle of the surface. A value of 1.0 means perfect mirror-like reflection lower values produce blurry or glossy reflections. For more information, see the Reflection Color example below. This parameter can be mapped with a texture in the Maps rollout. Note that the reflection color dims the diffuse surface color based on the Energy preservation mode option. Reflect – Specifies the amount of reflection and the reflection color.
