OctaneRender’s render passes have been larely replaced by the more modern AOV system. However, the Classic Render Pass mothodology can still be accessed. Render passes are processed differently by different render engines. Since OctaneRender is a separate render engine it also uses its own set of Classic Render Passes and these can be found under Blender’s View Layer Properties tab where there is an option between Classic Render Passes and Render AOV Node Graph (Figure 1).

The Preview Pass Type selects the pass that will rendered on the live render view (Blender 3D View window Rendered Viewport Shading method) or in the final render view (F12). The default Combined pass is the main beauty pass.
