Tutorial 2: An in depth look at the Transform Node (20:10 minutes)

As well as detailing all the features of the transform node this tutorial includes an introduction to the parameters window, creating custom parameters, using variables in expressions and creating a simple HDA (Houdini Digital Asset) which is a tool you can create, reuse and share.

The Expressions used in this tutorial are summarised in a handy cheat sheet, along with a list of global and local variables

If you want to recreate the scene shown here I have provided the Dutch House models shown in the video, which you can download below. There is also a copy of the completed scene and HDA.

  1. Awesome stuff, all crystal clear and well designed learning experience <3
    I think it is useful to mention also that when creating the custom parameter to control the scale of the buildings, it is important to activate the option "Use menu item token as value" (or "use token as value" in version 19.)
    Not doing that provides the index value of the menu item (0, 1 or 2) rather than the desired scaling factor, which causes the issue with the disappearing of the building when picking the first option.
