Using Groups

This tutorial looks at how to create and use groups in Houdini. It covers the group node, the group range node, the group transfer node and the group combine node.

We take a look at group syntax which can be used to add patterns of components to groups.
The documentation for group syntax is here:
https://www.sidefx.com/docs/houdini/model/groups.html

In exploring the group node the tutorial uses different kinds of groupings to create a chess board that has the positions of the pieces driven by rows and columns as used in chess notation ( https://en.wikipedia.org/wiki/Chess_notation )

The final piece was made into a Houdini Digital Asset which is included in the links below.

Houdini Kitchen tutorials are aimed at experienced 3D artists who are new to Houdini, and focus on creating procedural geometry for video games. Each tutorial covers a single node or concept, and will usually finish with a demonstration of how that tool might be used in asset creation. There are easier ways to use Houdini – commonly used nodes can be set up automatically using shelf tools, and useful networks are now embedded in higher level nodes – but I believe that to be able to fully harness the power of Houdini it is important to understand the basics. I have worked as a Technical Artist in the Video Game industry for 15 years, and my credits include Killzone 2 & 3, The Getaway 1 & 2 and Playstation VR Worlds. I have been learning Houdini since 2005, and have been using it in production for the last 5 years. I also have a degree in Archaeology and have completed several 3D projects for the British Museum.
