Houdini 19.0 Nodes Render nodes

Labs Texture Sheets 2.0 render node

Render an image sequence and assemble it as a single sheet (subUv, flipbook)

A common workflow is to render out an image sequence and then assemble the sequence into a single sheet using the Mosaic node.

This node automates that process by combining the whole process into a single button, it also allows to render out normal maps both through the volumes or RGB lights.
