Houdini Screen Attribute Visualization Tool: DF_AttrViz

Tool Description

DF_AttrViz is designed to visualize specific attribute values directly on Houdini’s viewport. It allows users to display attributes at a chosen level of a model hierarchy and for a specific index, making it easier to isolate and observe parameters. The tool supports real-time updates, multiple attribute selections, and customizable display settings, such as position and distance control, offering a seamless and intuitive way to interact with attribute data.

Parameter Description

• Attribute Settings: Controls the number of attributes to display. Click the plus icon to add new attributes.
• Attribute Type: Defines which level of attributes to view. Currently supports point, prim, and detail levels.
• Index: Specifies the index of the attribute value to display. This parameter is ignored if the detail level is selected.
• Attribute Name: Enter the name of the attribute you wish to display.
• Custom Prefix：If checked, the prefix displays your custom name.
• Prefix Name:Here enter the prefix name you want to customize the display.
• Prefix Widt：Controls the distance between property values and parameter names.
• Font Size: Adjusts the scale of the text. For multiline displays, use this in combination with line height.The text displays most clearly when the font size parameter matches the Global UI Scale setting in Houdini’s Edit → Preferences → General User Interface menu. If the font size exceeds this value, the text may appear blurry. You can temporarily increase the UI Scale setting for capturing screenshots or renders and restore it afterward.
• Text Width: Sets the distance between the attribute value and its parameter name.
• Text Position: The first value controls the X-axis position, and the second value controls the Y-axis position of the text.
