I've made a vector render in blender and it looks great! Problem is that there's too many nodes in one part of it. The path below is made up of 28 nodes.



I eventually brought that number down to about 8 but that was only by manually selecting each path, joining it (ctrl+k) and then selecting to overlapping endnodes and then joining them.

Is there a way to join multiple end nodes at one time or to automatically join overlapping nodes?

Not at the time, but I do think there is a similar request has been noted.

Maybe you can draw (trace) a new path using Bezier tool (only two nodes if you like) and delete the old ones.
