This tutorial describes how to use point attributes to influence upstream input nodes:

  • first using the traditional Copy Stamp Node (at 01:30 minutes)
  • then again using the Foreach Loop nodes as recommended by sidefx (at 15:35 minutes)

Then it takes an in depth look at the other uses of a Foreach loop:

  • Looping groups of points based on an attribute (at 38:17 minutes)
  • Looping through connected pieces (at 45:30 minutes)
  • Looping a set number of times (at 57:25 minutes)
  • Creating fractals (at 64:50 minutes)



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.
