[Closed] control the opacity of many splines

I have line object which contains a few hundred splines and I want to make each of this splines visible at a different time. How can i do that using maxscript?

The only way i know is to apply a checker map in the opacity slot, adding an unwrap_uvw and animate the vertexpositions in the unwrap_editor. It looks like this:

“sp” is the line object and “alines” is used to get the time when a spline should bekome visible

uvw = unwrap_uvw()
  addmodifier sp uvw
  select sp
  vcount = getnumverts sp
  vps = vcount/alines.count
  animate on
  (
     for r=1 to vcount do
     (
  	  sn = (r-1)/vps+1
  	  vvist = (alines[sn][1].keys[2].time as string) as integer
  	  uvw.setvertexposition (vvist-1) r [0.1,0.9,0.5]
  	  uvw.setvertexposition vvist r [0.9,0.9,0.5]				
  	)
  )
  mat = standard()
  mat.opacitymap = checker()
  sp.material = mat
  

The problem is, for a few hundred or a few thousand splines this is really slow.
Is there a more efficient way?
