The Base Component has no panel parameters and no 3D object parameters. You would use it for a component that has no panel associated with it, nor any 3D, such as component that converted RGB channels to HSV channels.

Parameters - Common Page

The Common parameter page sets the component's node viewer, clone relationships, Parent Shortcut, and Global OP Shortcut.

Parent Shortcut parentshortcut - Specifies a name you can use anywhere inside the component as the path to that component. See Parent Shortcut.

Global OP Shortcut opshortcut - Specifies a name you can use anywhere at all as the path to that component. See Global OP Shortcut.

Node View - Determines what is displayed in the node viewer, also known as the Node Viewer. Some options will not be available depending on the Component type (Object Component, Panel Component, Misc.)

  • Geometry Viewer - Shows a 3D geometry viewer displaying the geometry inside the component. This option is only available for Object components.
  • Control Panel - Displays the Control Panel, only available for Panel Components.
  • Operator Viewer - Displays the node viewer from any operator specified in the Operator Viewer parameter below.

Operator Viewer opviewer - Select which operator's node viewer to use when the Node View parameter is set to Operator Viewer.

Enable Cloning enablecloning - Control if the OP should be actively cloned.

Clone Master clone - Path to a component used as the Master Clone. If the component specified as Master exists, then this component becomes a clone.

Load On Demand loadondemand - Loads the component into memory only when required. Good to use for components that are not always used in the project.

External .tox externaltox - Path to a .tox file on disk which will source the component's content upon start of a .toe. This allows for components to contain networks that can be updated independently of the .toe file. Paths used to locate .tox files should not contain expressions or root variables. Built-in and Environment variables (like $MYDOCUMENTS, $DESKTOP and $HOME) are accepted. If the .tox file can not be found, whatever the .toe file was saved with will be loaded.

Reload .tox on Start reloadtoxonstart - When on (default), the external .tox file will be loaded when the .toe starts and the contents of the COMP will match that of the external .tox. This can be turned off to avoid loading from the referenced external .tox on startup if desired (the contents of the COMP are instead loaded from the .toe file). Useful if you wish to have a COMP reference an external .tox but not always load from it unless you specifically push the Re-Init Network parameter button.

Save Backup of External savebackup - When this checkbox is enabled, a backup copy of the component specified by the External .tox parameter is saved in the .toe file. This backup copy will be used if the External .tox can not be found. This may happen if the .tox was renamed, deleted, or the .toe file is running on another computer that is missing component media.

Sub-Component to Load subcompname - When loading from an External .tox file, this option allows you to reach into the .tox and pull out a COMP and make that the top-level COMP, ignoring everything else in the file (except for the contents of that COMP). For example if a .tox file named project1.tox contains project1/geo1, putting geo1 as the Sub-Component to Load, will result in geo1 being loaded in place of the current COMP. If this parameter is blank, it just loads the .tox file normally using the top level COMP in the file.

Re-Init Network reinitnet - This button will re-load from the external .tox file (if present), followed by re-initializing itself from its master, if it's a clone.

Parameters - Extensions Page

The Extensions parameter page sets the component's python extensions. Please see extensions for more information.

Internal Shortcut inshortcut - This parameter allows the component to be referenced by any children within it. For example if this parameter contains abc, then any child may quickly refer to this component with the expression:, regardless of how nested the child operator is.

Extension Object [1-4] extension[1-4] - A number of class instances that can be attached to the component.

Extension Name [1-4] extname[1-4] - Optional name to search by, instead of the instance class name.

Promote Extension [1-4] promoteextension[1-4] - Controls whether or not the extensions are visible directly at the component level, or must be accessed through the .ext member. Example: n.Somefunction vs n.ext.Somefunction

Re-Init Extensions reinitextensions - Recompile all extension objects. Normally extension objects are compiled only when they are referenced and their definitions have changed.
