Not sure if you missed my point,
So just to clarify
If a large spline is laid out with all mesh elements set to null it can be edited easily.(great)
If you lay out a large spline with mesh elements … editing is extremely difficult. (to be expected)
If then all mesh elements are subsequently set to null… no difference is seen (strange)
The conclusion being that setting mesh elements to null is not clearing the references to meshes
This worries me If the references are not being cleared, it could well cause problems further down the road ( pun)
Also for your consideration
I have only seen end meshes available with 3 sockets Left, Up, Right
Consider having “n” amount of sockets eg Left1, Left2, Up , Right1, Right2, Right3
