If you want different meshes to be placed along the spline, then you could create an array of splinemesh components and as you loop though the for loop, use the mesh at the that point in the array using the same loop number to index into the array. You would have to create as many elements in the array as you have points though.
I did set up a version of the graph where it gets the length of the spline and equally spaces out meshes using the ‘get world point at distance along spline’ (or whatever its called) along with the tangent version, but the meshes didnt get deformed properly along the spline. they were deformed at the start and end points but the deformation quickly fell off along between mesh division so it wasn’t really usable to get smoothly deformed geometry. I’d like to hear from someone at epic about how to get that working. I’ll want to investigate further but dont have much time at the moment.
If you want just a single mesh deformed, then create a single splineMesh component in the blueprint component tab and connect the start and end positions and tangents directly to that spline mesh by getting a reference to it. If you watch the video where I demonstrate that with a plane, then that is how you do it.
