Copy Hierarchy

When invoked, the selected bone and all of its children are copied along with goals and targets if you choose. The copied hierarchy will appear next to the selected bone but slightly offset. The parent of the newly created copy will be the same as the copied bone’s parent.

  • Root of Hierarchy to Copy - Displays the selected bone that is the root of the hierarchy that you want to copy.
  • Copy Goals, Item Shapes, Targets - Select YES if you want any of these copied and NO if you only want the bones in the hierarchy copied.
  • Name Edit Method -
    • Add Prefix/Add Suffix - The user interface panel allows you to add a Prefix or Suffix. You can type in your own into the Prefix/Suffix to add to Bone Names text box. Or choose one from the Prefix/Suffix to add to Bone Names pop up menu.
    • Replace String - You also can choose to replace an existing text string in the original hierarchy with a new text string. Type the string you wish to replace into the Replace this String text box and the string you want to replace it with into the With this String text box.

Export RIG

(default keyboard shortcut Shift J)

(Setup > Edit > Export RIG) With Export RIG (hierarchy) you can select a parent bone of a hierarchy or an object containing a hierarchy and export it for future use in another mesh. You can export goals, targets and keep the custom item’ shapes that may have been added.

What’s Exported?

Most settings applied to the hierarchy will be exported. IK settings and other properties will go along with the RIG file. See the note below for limitations.

With this first release there are limitations to what can be exported from the rig.

The motion modifiers that make up many of the rigs used right now are not supported, but will be very soon. A new scheme to allow plugins to communicate and share their settings data will be added. The first to have this done is the ItemShape plugin that allows you to customise the way Nulls and other objects are displayed. This allows the RIG file format to read the data directly from the plugin. As the other plugins add this feature, the RIG file format will be able to export and import ALL items and settings used in rigging a character.

Root of Hierarchy to Export

Displays the parent or root of the hierarchy to be exported.

Browse Export File:

This will open a file requester so you can choose a place to save your export.

Description of Rig to Export

Enter a useful description about the export so you will know what you have when you import this file back into LightWave.

Export Goals, ItemShapes, Targets.

Select YES if you want to export goals and targets along with the bones. To export a hierarchy from a selected bone:

 

  1. Select the bone that is the parent of the hierarchy you wish to export.



  2. Run Setup > Edit > Export RIG and the dialog box will appear.


  3. Browse to the folder you wish to export to and choose the settings.


  4. Click OK.

Delete

Delete Hierarchy

(Setup > Edit > Delete > Delete Hierarchy).

When invoked, the selected bone and all of its children and grandchildren, etc. are deleted, leaving all other bones in place.

Delete Bone

  • Bone To Delete - Displays the name of the selected bone.
  • Parent Child Bones -
    • to Deleted’s Parent - Will parent the remaining bones (if there are any) to the deleted bone’s parent.
    • to Object - Will parent the remaining bones (if there are any) to the object.

This operation cannot be undone.
