A definitive solution for spline mesh twisting (gimbal lock)?

Hi, I’m attempting to create a spline mesh that does not exhibit the classic ‘twisting’ issue. I’ve tried a number of methods, but have yet to have success in 5.3.

I’ve tried Chris Murphy’s:

I’ve tried this code: https://www.reddit.com/r/unrealengine/comments/kqo6ez/usplinecomponent_twists_in_on_itself/

And yet, a spline mesh that bends in Z still exhibits twisting (these solutions all seem to make it actually worse). As I am working in 2D space, I’ve simply resorted to working on the X/Y plane and then rotating the actor containing the spline mesh to make it vertical. Not optimal, but I’ve reached the end of my rope on this.

Any tips greatly appreciated.

I don’t think there is a solution, because the twist is imparted by the editor interface code, as you add new points…

Ok. I’m a bit confused though, as it appears both of those code blocks promise to resolve the issue?

But they don’t, right?

I think they would have to compensate for the unnecessary twist added by the editor, not easy.

So the solution is no solution. Zen vibes.

Yes, the solution is the space where the solution will be…
