Houdini 20.0 Nodes Geometry nodes

Stroke Cache geometry node

Simplifies the building of tools that incrementally modify geometry based on strokes.

This node type is deprecated. It is scheduled to be deleted in an upcoming revision of Houdini.

Use the Stash node instead.

(Since version 17.5.)

Since 14.0

This node records strokes using the Stroke State Stroke SOP. The Geometry plugged into the first input is run through a For Each SOP, with one iteration per recorded stroke. Within this For Each, it’s possible to set up a SOP network that modifies the input geometry based on the shape and attributes of the recorded stroke.

The geometry is cached after each stroke, so that each stroke only requires the For Each to cook for that one new stroke.
