Hi,

You can add the AximmetryAR tag to multiple selected Actors or groups of Actors simultaneously, provided they don't have other tags. If any of the selected Actors have different tags, you won't be able to add the AximmetryAR tag.

In scenarios where some Actors already have the AximmetryAR tag, and you're certain they don't have other types of tags, you can click the bin button to remove all existing tags:

After doing so, you can add the AximmetryAR tag to every selected object in the same way you would add it to a single Actor:

Note, to select multiple Actors in Unreal's Outliner panel, hold the SHIFT or CTRL key while clicking on the Actors.

Additionally, you can dynamically add tags using Blueprints. To learn how to do this, please read the following documentation: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/ar-production/aximmetry-de-scene-setup-ar/#dynamically-spawned-models-and-actors

Warmest regards,
