HRESULT | OnGeometryIdentificationStreamsAdded (IRcUndoRedoGroup *pUndoRedo)

## Detailed Description

This interface is implemented by mesh modifiers that require notifications about changes of geometry identification stream; like recalculation of unwrap, so that modifiers can update representation to new unwrap if needed.

HRESULT IRsGeometryIdentificationNotify::OnGeometryIdentificationStreamsRemove | ( | IRcUndoRedoGroup * | pUndoRedo | ) |

Notify modifier node that geometry streams will be removed. As a response, modifier should store it's parameters in representation that is not dependent on geometry streams.

Parameters:

  | pUndoRedo | [in] Container for collecting commands for undo/redo processing.

Returns:
  Standard HRESULT processing can be applied.

HRESULT IRsGeometryIdentificationNotify::OnGeometryIdentificationStreamsAdded | ( | IRcUndoRedoGroup * | pUndoRedo | ) |

Notify modifier node geometry streams were added again and it can turn it's properties to geometry identification streams dependent representation.

Parameters:

  | pUndoRedo | [in] Container for collecting commands for undo/redo processing.

Returns:
  Standard HRESULT processing can be applied.
