Thanks for your reply.
I was able to get the spline to deform a single mesh but I am getting a similar result to what you describe where the mesh would deform to the start and end point but middle part of the mesh wasn’t deforming along the spine correctly (if at all really it just looks like the mesh is snapping to the start and end).
In my previous post I was trying to sort out how to get the last point index from the curve without having to manually set it in the blueprint. I thought I could do this by using “GetNumSplinePoints” and plugging this into the point index for end position but this doesn’t appear to work.
