Houdini 18.0 Nodes TOP nodes

Map by Index TOP node

Maps upstream work items to downstream work items based on their index.

On this page

This node maps upstream static or dynamic work items to downstream static items based on their index.


Use Dynamic Mapping

By default, a mapper will establish dependencies between upstream static work items and downstream static work items. When this toggle is enabled, a second mapping pass will be done between any dynamic items above the mapper and static items below the mapper.

The dynamic items will be prefiltered based on the static mapping defined by the node, such that only dynamic items that descend from the selected static items will be considered.
