Thank you for your response, RecourseDesign
Yeah, I’m thinking about that. But if it could be done in BP, maybe there is a way in c++ too.

The most strange part is that the trigger sphere trying to attach to itself. But as I understand this in SetupAttachment(this) is referenced to the interaction component.
