Splines without a landscape

Hello, bit of a silly problem I have run into, but have not been able to find a solution for in documentation.

I’m creating an underground river / rapid with splines and a mesh / material. Problem I have is that I am only able to place splines within the bounds of a selected landscape actor. Just wondering if there is a way to be able to place them freely in space.

You create SPlines on terrains or into Blueprints, using SPLine nodes.

Hi Docjor,

By using Blueprint Splines you can achieve this.

In the Content Examples project from the Learn Tab you can open the Map Blueprint_Splines.umap to explore these setups with some examples.

Dokipen does a series of tutorials explaining these splines and getting them setup:
