I sincerely thank you for your availability. As for my intention, I would like to obtain the same result that is shown by this Russian guy in this tutorial: 01. Оптимизация уровня с помощью hierarchical instanced static mesh - YouTube
The problem is that from 41:50 and then it doesn’t show the individual rotation of the instances. It creates and deletes nodes so I don’t understand what should remain in the Event Graph.
Best regards
