OctaneRender® provides a unique rendering experience by interacting with the scene with a final render quality. This interactivity creates renders that might not be possible with traditional render engines. You can continue to hunt for that perfect camera angle where all the light reflections are just right, or you can continue adjusting the depth-of-field in real-time. You can manipulate the Render Viewport like traditional 3D viewports with rotation, panning, and zooming controls

Settings related to navigation and Viewport control mappings are managed in the Application and Controls tabs in Preferences.  To open these tabs, click on File > Preferences > Controls tab.
