5.  In the Volume-delay functions section, insert the desired VDFs (Selecting a VDF and setting the parameters).

6.  In the Node types section, allocate the numbers of the desired VD functions to the node types in the VDFNo (VD functions number) column.

Note: The table shows the allocation of VD functions to node types. Use the symbol to group the view of the nodes types by global types and allocate the same VD function to all node types of a global type. Use the to ungroup the groups.

7.  Confirm with OK.

The changes are applied.
