Growing splines keeping clean geo?

Hi there,

I'm having a hard time trying to figure out how to create a growing spline animation and keep vertex position as clean as possible.
Here's the scenario. I want to export an obj sequence to use it in AE-Plexus.
Everything seems to work just fine, when I apply a noise modifier in Plexus though points get funky and start to animate crazy, jiggling and moving all the time.
I found out that what's causing this is issue is the way I'm animating the growing spline in 3ds Max. At first I've tried a path deform, but that doesn't work as there are only two option I'm aware of: 1, stretch the shape and 2, percent. If I use stretch, the geo is not actually growing, is just being stretched. The percent simply moves the shape along the path. What I do need, instead, is an actual creation of vertexes over time.
Then I tried the Slice modifier, it seemed to work a bit better, except for my case where the spline path is not straight, therefore anytime the spline makes a curve the Slice is not following the curvature (unless I animate it manually, but that's crazy and still not accurate).
Boolean didn't work either.
Also animating the scale on a Loft compound is not the solution, as the mesh still is the same across the duration of the animation, just being scaled not actually created over time.

Not sure what I'm trying to explain is clear enough, to better explain what I'm trying to achieve here are a few screen grabs from C4D viewport. This is the solution I'm looking for:
