The OctaneRender® Viewport window is where you will do all your render work. The view will dynamic change to follow your active 3DS Max® Viewport. You can save your final still renders from here. For animation, use the standard 3DS Max® render window. For beginners, the main tools to understand are the Save Image and Lock Camera button.
Save Image - Saves the current render from the OctaneRender® Viewport to disk.
Lock Camera - Locks the camera for the 3DS Max® Viewport that you want to render. If you disable this function, 3DS Max® restarts the render each time you select a different 3DS Max® Viewport.
