KTT

A Houdini node shape with the Houdini icon
toolset icon design

July 2025 - September 2025

Kruger trusted me for designing the icons required for each of his custom nodes that are part of his "KTT" toolset. The toolset allows for advanced 3d terrain creation in the Houdini software. I was in charge of designing the main logo and the icons for each of the 50 nodes.

The project was especially interesting because it was not the usual allegoric icons where you need to represent an action. Instead, we focus on the result of the action, and for a tool that generates terrains, this mean creating a lot of small environment scenes !

The icons are usually viewed at very small size so it was tricky to make such detailed scenes readable in all contexts.

in context

This is how the nodes looks in Houdini when zoomed in. Keep in mind they are usually viewed at even smaller scale !

Also, here is 2 random details about Houdini node's icons:

  • images must have an embed ICC profile, else they will be displayed darker.
  • the ideal size for PNG icons is 49x49px; SVG is also supported but have a slightly aliased rendering.

This is the first full iteration of the logo which we discarded in the end.

the first KTT logo iteration with a light theme. the first KTT logo iteration with a rocky colored theme. the first KTT logo iteration with a strata background and the same colored theme.
