Expanding on Endless Runner tutortial - Spawning tiles on Y axis?

Hello all!
New Unreal user here, and I’m finding it much more intuitive/productive than Unity so far! I’ve completed the endless runner tutorial (Endless Runner: Overview & Player Control | 01 | v4.7 Tutorial Series | Unreal Engine - YouTube), and am trying to expand it some by adding tiles to the left and right of the character, but I haven’t figured out a way to implement that yet. I think what i’m trying to do is set the actor’s spawn rotation so that the Y can move, but not rotate into itself. I’ve added 2 new attach points to the BPtile, and everything else is roughly the same.

I’ve attached some screenshots of my blueprints, if someone can please review it and try to send me down the right path, I’d appreciate it very much!

Thanks!

Does anyone know how this might be done? I’m assuming there might be a way to call the floor constructor script on the Y axis, but I don’t really have an idea how to call that yet…?
