Rotate floor sections

I want to rotate a section of the floor 90 degrees when the player steps through a trigger box. I’m a noob when it comes to blueprints and have tried adapting solutions similar to mine with no effect.

Is the floor inside a BP? If so, add a collision box and set the mesh to rotate when the player overlaps.

If it’s just a static mesh in the level, then you’ll have to add an OnActorBeginOverlap for the trigger box into the level BP, then reference the cube and rotate it.

Both do the same. Don’t forget to set the mesh to moveable.
