Houdini 16.5

Tag visualizer

Displays a selectable label pointing to an object, even when the object is offscreen.

This can be useful for annotating objects in the scene for artists, or making large selection targets for small, hard to select, or far-off objects.

See visualizers for more information.

Parameters

Contents

Style

Whether the tag contains text, an icon, or both.

Text source

Where to get the tag text. You can use the object name, a fixed string, or the value of a detail attribute from the object’s geometry.

Icon source

Where to get the tag icon. You can use the object’s icon or choose an image file.

Behavior

Preferred placement

Where to put the tag when all sides are available. If there’s no room in the viewport to use this side, Houdini will automatically display it on a different side.

Clicking tag selects object

Clicking the tag will select the object. Turn this off to make the tag unclickable.

When object is offscreen

Keep tag in viewport

Display the tag even when the object is not in view. This is useful for selecting objects in the viewport when they're not visible.

Show icon only

When an object is not in view but the tag is displayed, only show the icon. This helps reduce tag clutter. (How to tell what object tag is for???)

Appearance

Font

Font for the tag text.

Font size

Size of the tag text.

Icon size

Size of the tag icon.

Text color

Color for the tag text.

Frame tagged object

Show a frame around the object in addition to the tag.

Frame color

Color for the frame around the object.

Background color

Color of the tag background.

Corner radius

The radius of the rounded corners of the tag.

Padding

Amount of space between the tag edges, icon, and text.

  • Compositing

    Houdini’s compositing networks let you create and manipulate images such as renders.

  • Digital assets

    Digital assets let you create reusable nodes and tools from existing networks.

  • Import and export

    How to get scene, object, and other data in and out of Houdini.

  • MPlay viewer

    Using Houdini’s stand-alone image viewer.

Nodes

  • Object nodes

    Object nodes represent objects in the scene, such as character parts, geometry objects, lights, cameras, and so on.

  • Geometry nodes

    Geometry nodes live inside Geo objects and generate geometry.

  • Dynamics nodes

    Dynamics nodes set up the conditions and rules for dynamics simulations.

  • VOP nodes

  • Render nodes

    Render nodes either render the scene or set up render dependency networks.

  • Channel nodes

    Channel nodes create, filter, and manipulate channel data.

  • Compositing nodes
