PBR map: Albedo, Basecolor, or Diffuse Specular Channel This channel should be set to have no contribution (color of H:0, S:0, V:0, and float=0) when making a Transmissive (glass/sss), Emissive (light-emitting), or RGB IOR type metal. This channel can be controlled by float (0 = black, 1 = white), or by the Color picker, or by a Texture input. The Albedo channel (referred to as Diffuse in other apps and even other places in Octane) controls the overall color of a non-metallic opaque material (matte or glossy, like plaster, stone, wood, etc.) It also colors a metallic material which is using the Artistic IOR type. Emission alone makes a light-emitting material, and Transmission alone creates a translucent material like glass/water/wax/jade/etc. Metallic alone makes a metallic material. Albedo + Specular makes a glossy opaque material like plastic. Most of these channels should be an either/or situation, where the other channels in this section are turned off (have no contribution), so the material doesn't get muddy or difficult to work with.Īlbedo alone without any other contribution makes a perfectly matte material. The Albedo, Specular, Metallic, Emission, and Transmission channels control the material’s basic properties. If this is overwhelming, skip ahead, learn about all the channels, and then when you come back and reference this, it should make more sense. Below is a diagram that shows how the channels relate to one another. All Octane materials are broken down into channels, and the Universal Material has quite a few of them. The Universal Material was introduced in 2018, and remains the most versatile way to make nearly any type of material you can think of.
