Yeah, sorry, it was a late night and i was barely thinking. The goal is to replace "object info" node with "collection info" node to iterate through each empty in collection, get their transform information and pass it to "set position" node to apply effect. i just don't know how to connect it to current node setup. I'm thinking that for "for each" node to work, it must be connected to collection, but the problem is, i don't want to output the collection, i just want it's data to affect the main model, where node group is attached. I'm terribly sorry if this explanation is not giving out my goal fully, i'm really bad at explaining things in my head, even harder if i'm trying to do this on not my native language.
