The goal of this quick start article is to provide the three most relevant topics for getting started quickly in Octane for 3ds max. This includes the use of progressive rendering, illumination basics, and material design. For more detailed information, please reference the online documentation.
Activating the Octane Renderer
Octane is tightly integrated into 3ds max. Much of Octane's functionality can be found in the Render Setup window. The latest version of Octane now includes a menu item as well which can be used to set Octane as the current renderer (Figure 01).

Rendering with Octane
Once Octane is selected as the render engine, rendering with Octane is done using the OctaneRender Viewport (Figure 02).

The OctaneRender Vierwport can be accessed via the Octane menu (Figure 03a) or from the Render Setup window (Figure 03b).

The OctaneRender Viewport should be used to render while working on a scene. Scene elements such as materials, lights, and cameras will update in real-time inside this window. The Rendered Frame window does not allow for real-time updates. It will continue to render until it reaches the Max Samples specified in the Kernel settings. The Rendered Frame window is typically used to execute an animation rendering while the OctaneRender Viewport is used during the scene editing process.
Lighting in Octane
By default, there is no illumination present in a scene. Ambient light can be added to a scene by increasing the color or adding an HDRI texture map to the Background parameter in the Environment window (Figure 04).

Octane for 3ds max also provides access to three additional direct light sources. These lights can be accessed from the Lights subcategory of the Create Panel (Figure 05).

- Octane Daylight: In addition to providing ambient light in the form of a sky, this light type also provides a directional light source in the form of the sun (Figure 6a).
- IES Light: The Octane IES light source is similar to the Octane Light, however, it can accept an IES light profile. The IES light does not have light shape options (Figure 6b).
- Octane Light: This light type provides a finite light source with a host of shapes including plane, sphere, and disc (Figure 6c).

Materials in Octane
Octane-specific materials can be accessed and created from the Slate Material Editor. There are five material types available in Octane for 3ds max (Figure 07).
Figure 07: Octane Materials in the Slate Material Editor
- Diffuse: used for dull, non-reflecting materials or light emitting surfaces
- Glossy: used for shiny materials such as plastics or metals
- Mix: used to mix any two material types
- Portal: a special type of material that assists with bouncing exterior illumination into an enclosed space
- Specular: used for transparent materials such as glass and water
Octane also provides an online database with pre-made materials. The LiveDB can be access via the Octane menu (Figure 08).

Octane will only render its native material types. However, 3ds max materials can be converted to Octane Glossy materials using the material convert tool (Figure 10).
