Yeah, I think you got it! :smile:
When it says move the wheel node, I think it means just the move the wheel move, making sure the children nodes are not selected. I think it’s okay if the children are moved along with (because their parent moves). I think what they are trying to say is “select only the wheel node and move that node, making sure the children node(s) are not selected. The children nodes will move with the parent, so you don’t need to move them individually.”
I have to admit it’s pretty confusing. I haven’t needed to use VehicleBody nodes (at least, not yet) but even reading about it makes my head spin, so I’m probably not the best person to be giving advice about all this...
I think you’re on the right track!
