The Controls Settings

 

Settings related to navigation and viewport control mappings are managed in the Applications Settings and Controls Settings dialogs.  To open the Dialog, go to the File -> Preferences -> Controls tab.

 

 

The Preset dropdown box allows the user to quickly set OctaneRender™ navigation to behave like a number of common 3D modeling packages.

The actions of the scroll wheel when used within the Node Graph Editor pane can be set to either zoom or scroll.

There are also viewport (camera) navigation modes (rotate and roll) and a few are renamed in the application preferences.
