Overview ¶
The parameter editor lets you edit the parameters of the selected node to change how it works. However, sometimes there is a set of parameters that you want constant and easy access to. For example:
-
Parameters are on a deeply nested node that’s time consuming to navigate to.
-
You are constantly tweaking parameters from two different nodes and don’t want to switch back and forth between them.
-
You want to put some useful parameters from a character in the view so you can access them even with the view maximized and the parameter editor hidden.
HUD (Heads Up Display) sliders appear in the viewer and controls a parameter on a node. They can stay visible when the parameter’s node is not selected. You can group sliders together, move them around the view, and choose when they're visible.
How to ¶

HUD sliders are disabled when you use some Houdini tools such as View. If your HUD sliders appear dimmed, switch to another tool to re-enable the HUD sliders.
