Select Random

Reference

Mode:

Object Mode and Edit Mode

Menu:

Select ‣ Select Random

Adds random items to the selection.

Ratio

The ratio of items that should end up selected, e.g. 0.5 to select half of all items (that are not hidden).

Note that the existing selection is ignored: if half of the items are already selected, setting Ratio to 0.1 won’t deselect anything, nor will it select 10% of the unselected items. Instead, it always picks 10% of all visible items and adds them to the selection.

Random Seed

A number that influences which specific items get picked.

Action
Select:

Add random items to the selection.

Deselect:

Remove random items from the selection.
