The basic spline BP I made performs like ass lmao

@Voidie3D I know it's a whole new tool but you may get better luck with houdini HDA's or using Geometry nodes in Blender

Geonodes may not have live link tho :s

@VERTICALstudio Yeah I likely would be better off with HDAs but I've tried learning Houdini before and it didn't go well haha.
The poor performance (while editing) is 100% a result of me not being a tech artist anyway - doing it in another program won't fix that. I've used actually good spline tools made with BPs that work much better so I know it's possible here.
