Editor - Apply Spline - conforming a landscape to blueprint spline

Hi Everybody,

I have a blueprint road generator which has some custom functionality built in to make editing the track for my longboarding game much easier than traditional landscape splines.

I am trying to use the editor apply spline node in the construction script to conform the landscape to the track once I have designed it.

Problem 1:

Node Setup:

Landscape Deform:

The main problem I have, is that I can’t seem to adjust the “raise heights” or “lower heights” values as the input for the node is a bool.

I assume there must be a way to either:

1: Offset the road mesh by a value that brings it above the landscape. This is workable, but not ideal as the spline will be higher or lower than the road which makes editing the track less precise and efficient.

2: Adjust the landscape Raise / Lower Height values in the node so that the landscape correctly conforms to the spline.

I have tried to use landscape splines and it does work but is incredibly slow and is much harder to work with for my requirements.
In the landscape spline settings there is an option to offset the spline mesh so that it sits above the landscape correctly. However I’m working with large levels, and even with World partition any adjustments to the landscape spline are very slow.

I would really appreciate any input as to how best to acheive this.

Thank you!
