Materials

Octane For After Effects integrates the OctaneVR Standalone Interface along with all its elements and materials, providing After Effects users the ability to harness the power of OctaneVR's node-based editing system.

There are five types of materials in Octane which can be applied to surfaces to achieve a variety of surface appearances and rendering effects.

• 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 rough, non-reflecting materials, as well as light emitting meshes.
• 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.
• 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.
• Mix — Used to mix 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. — Used to designate openings in scenes to allow the render kernel to better sample light from those areas.

MaterialsA set of attributes or parameters that describe surface characteristics. can be accessed via the OctaneVR Nodegraph Editor.

Opening the Nodegraph via the Object Settings

This allows users to edit existing materials and also create new materials by working with the Octane node tree in the Octane Interface. To do this, click on Object Settings > Object > Object Nodegraph > Edit button (figure 2).

Once the Octane Interface is opened, existing materials can be edited or new materials can be created. Right-click on an empty area in Octane’s Nodegraph Editor to invoke the context menu, hover on Materials to see the five Octane native materials available (figure 3).
