Materials

There are 14 types of materials available in OctaneRender^®:

Clipping - Used to cut one shape from another much like a Boolean subtraction function.
Composite - Mixes several MaterialsA set of attributes or parameters that describe surface characteristics. using masks.
DiffuseAmount of diffusion, or the reflection of light photons at different angles from an uneven or granular surface. Used for dull, non-reflecting materials or mesh emitters. - Used for dull, non-reflecting Materials or Mesh emitters.
GlossyThe measure of how well light is reflected from a surface in the specular direction, the amount and way in which the light is spread around the specular direction, and the change in specular reflection as the specular angle changes. Used for shiny materials such as plastics or metals. - Used for shiny Materials such as plastics or metals.
Hair - A dedicated shader with real-world physical characteristics that describe hair interaction with light.
Layered - A system that uses dedicated material layer types found in the MaterialThe representation of the surface or volume properties of an object. Layers roll-out to construct complex surfaces.
Metallic - Similar to the Glossy materialUsed for shiny materials such as plastics or metals., except by default it exhibits more metal-like characteristics.
Mix - Mixes any two Material types.
PortalA technique that assists the render kernel with exterior light sources that illuminate interiors. In interior renderings with windows, it is difficult for the path tracer to find light from the outside environment and optimally render the scene. Portals are planes that are added to the scene with the Portal material applied to them. - Designates openings in scenes to allow the render kernel to better sample light from those areas. For more information, see the Lighting topic in this manual.
Shadow CatcherThe Shadow Catcher can be used to create shadows cast by objects onto the surrounding background imagery. The shadows cast are not limited to simply a ground plane but can be cast onto other surfaces of varying shapes. - A dedicated material that captures shadows.
SpecularAmount of specular reflection, or the mirror-like reflection of light photons at the same angle. Used for transparent materials such as glass and water. - Used for transparent Materials such as glass and water.
Standard Surface - This material closely aligns with the Autodesk Standard Surface shader specification for cross-application interoperability.
Toon - Designs surfaces that look hand-drawn.
Universal - Integrates more closely with PBRA contemporary shading and rendering process that seeks to simplify shading characteristics while providing a more accurate representation of lighting in the real world. workflows.

Additionally, the Material Selector and the Material Switch nodes can be accessed from this menu. These node types are also covered in this section.

You can access the OctaneRender materials by expanding the Octane rollout in the Materials section of the Slate Material Editor (figure 1).
