So, I understand the concept of instancing collections.
My question is now, when I have a several placeholder objects (simple cube), how could I link certain instanced collection to all of those selected placeholder meshes? Something like applying modifiers to all selected objects?
I want to be able to realize those instances and have hundreds of individual objects from just a few dozens of placeholders with already precise positioning and angles.
Edit.: I figured it out now. When instanced collection was created, I added geonode with instanced collection to it. After just selected all placeholders (cubes) and then just realized instances. That did the trick without assigning that instanced collection individually to each cube. Which was my main goal here.
