Randomize Attribute

The Randomize operator assigns a random value within a configurable range to the attribute on all selected elements. Each element gets its own independently generated value.

It is useful for things like:

• Scattering random instance_index values across faces to vary spawned props in Geometry Nodes.
• Giving every vertex a random color for procedural variation.
• Randomly tagging a percentage of faces with a boolean flag.

Where to Find It

Randomize is available in two places when you are in Edit Mode on a mesh object:

• Properties Editor → Mesh Data → Attributes, below the attribute list.
• Right-click context menu of any attribute field in the Attributes panel or the Ctrl+D popup.

How to Use

1. Select the elements (vertices, edges, faces, or face corners matching the attribute's domain) you want to randomize.
2. Click Randomize for the attribute you want to change.
3. Configure the random range in the dialog and confirm with OK.

Options per Attribute Type

The dialog adapts to the type of the attribute being randomized:

• Booleans - a Probability slider controls the chance of each selected element being set to True.
• Integers & Floats - a Min / Max range the random values are drawn from.
• Vectors - a Min / Max range for each component. Individual components (X/Y/Z) can be toggled off - disabled components keep their current value.
• Colors - choose between the RGB and HSV color model, then set a Min / Max range (0-1) per channel. Individual channels (including alpha) can be toggled off and keep their current value.

Info

String attributes cannot be randomized, as random text is rarely useful.
