SideFX Labs Toolset (as of Hou 18.0.532)

The SideFX Labs Toolset library.

“One piece of software can’t meet all the challenges you face in a day. Houdini can be the backbone to your pipeline, allowing other packages to send and receive assets to streamline your pipeline. SideFX Labs provides integrations that include support for photogrammetry, lookdev, texture generation and more.”
