Installing the OctaneRender® for Unity® Integration


You can install the OctaneRender® for Unity® integration by downloading one of the scenes OTOY® provides in the Unity Asset Store. The Installer Scene is built to be lightweight and friendly, so we recommend it for getting started (Figure 1).

You can also import the Installer Scene directly from Unity's Asset Store and into a project (Figure 2).

After the download is complete, the Import Unity Package window opens. Click the Import button to import all the contents from the Installer Scene into the current Unity project (Figure 3).

Once the Installer Scene is imported, select the PBR Render Target in the Hierarchy window (Figure 4).

After clicking the Load Octane button and activating the Octane render engine, the Inspector window provides many rollouts for controlling the render process. To start the rendering process, click the Render button (Figure 6).

Clicking the Render button opens the PBR Viewport window, where the rendering process continuously updates until OctaneRender reaches the specified sampling level (Figure 7).

The Installer Scene contains the OctaneRender for Unity plug-in, which you can import into any Unity scene as a custom package without the additional assets contained in the Installer Scene. To accomplish this:


  1. Create a new Unity scene, then from the Assets menu, choose Import Package, then click Custom Package (Figure 8).
