Customizing the Houdini Interface

Houdini provides almost limitless customization, it's easy to be overwhelmed at first as there's lots of different places where you change settings.

Outlined below are the steps I take to customize Houdini to my liking.

Get the Slate Theme

To get a flat user interface, I'm using this Slate Theme from Odforce I found a while ago. It eliminates a lot of the shading on UI elements like buttons and tabs. I find it easier on the eyes as well as more simplified modern look.

The theme can be downloaded here Slate_Theme_Houdini.zip, unzip the files and put them in your $HOME/houdiniX.x/config/ directory. The next time you launch Houdini, you should see the Slate theme as an option in your Edit ► Color Settings Window

Changing the Desktop Layout

Download this JK.desk file and place it in your local preferences desktop directory $HOME/houdiniX.x/desktop/

You can switch between desktops using the menu at the top of the main window

By default Houdini starts up in the Build desktop, but you can change that in the Edit ► Preferences ► General User Interface

Simplifying Node Shapes

In the network editor pane, click the View dropdown menu

Show Custom Node Shapes ► Disable, so all nodes are rectangular

In the network editor pane, click the Tools dropdown menu

Make Room for New Nodes ► Disable

In the main Houdini prefs, Edit ► Preferences ► Network Editor, Nodes and Trees

Use simplified shape when node shapes ► Enable, uses an even simpler default node shape (a simple rectangle instead of a rounded rectangle)

Animate network changes ► Disable

Press the "d" key with your mouse over the network pane to raise the Network View Display Options

General Tab ► Node size to show ring ► never show the ring

Themes Tab ► Default node colors ► Disable

Changing the Splash Screen

Some aspects of Houdini can only be customized through Setting Houdini Environment Variables.

You can customize the following Houdini Environment Variables by editing $HOME/houdiniX.x/houdini.env

HOUDINI_SPLASH_FILE = ~/hsplash/hsplash_014.png
HOUDINI_SPLASH_MESSAGE = "Welcome//n${USER} @ ${HOSTNAME}//n${HOUDINI_VERSION}//nGood Luck!"

HOUDINI_ANONYMOUS_STATISTICS = 0
HOUDINI_LMINFO_VERBOSE = 0
HOUDINI_ENABLE_OLD_PRESETS = 1
HOUDINI_USE_OTL_AS_DEFAULT_HDA_EXT = 1
HOUDINI_MAX_FILE_HISTORY = 32
HOUDINI_UI_QUEUE_SIZE = 2500000
# When enabled, Houdini will output OpenCL memory usage statistics after every set of OpenCL kernel calls.
