OctaneRender® supports three object visibility properties for Mesh object visibility. You can find these by right-clicking on a scene Object and selecting Object Properties from the Quad menu.
Visibility - Setting the value to 0 makes the Object invisible. Setting the value to 1 makes the Object visible.
Visible To Camera - When disabled, the Object casts a shadow, but the Object's surface is invisible to the camera.
Cast Shadows - When disabled, the Object won't cast a shadow, but the Object's surface is visible to the camera.
