Hmm No effect it didn’t change the spline line direction which is strange… I seem to have different nodes to whats in your setup. because I’m using ver 4.14 and the setup I got was from a youtube tutorial on how to construct a spline so I don’t know if I have been given the correct setup or not for the Engine version I’m using… I’ve only got the S Spline in the components list, there’s no sm static mesh variable in my setup. You also have several other extra variables included that I don’t have in my setup under defaults like Mesh Length and Mesh Collision. and Allow Stretching.
You’ve also got your index set to 1 while I have to have mine set to 0 or it won’t show up the spline mesh. if I dont have my spline location set to relative, and try to set it to world then the spline mesh won’t show. So my setup is not compatible with yours, so I’ll try your setup instead, but I need to see the components list to add the extra variables I need to set up your spline.
