Why can't Landscape Splines be referenced in Blueprints at all?

I’m seriously angry about this. Why can’t Landscape Splines be used in Blueprints?

This is a very important element in incorporating gameplay into the landscape. It is one of the few methods that can provide both spline information and the terrain along it at the same time. Why does the editor restrict access to this spline?

I think this is harassment of Blueprint users. It makes no sense that they don’t even allow access to spline points. Maybe they were aiming to eventually move to Blueprint brushes, but the performance is a world apart.

It’s already 2026. Isn’t it about time we implemented the minimum functionality?
