Hi Jeroen:

I was checking this (old) new feature here at the studio and we notice
that the index mat is not working.
I go through the original patch (the one ask for Plumiferos) and I
found that the commit that you did skip
a couple of things:

1 )
The original revision:
http://projects.blender.org/scm/viewvc.php?view=rev&root=bf-blender&revision=38090

If you check the to "rendercore.c" you use:
  *fp= (float)shi->mat->index;

but is:
  *fp= (float)shi->vlr->mat->index;

2)
There is a missing function on zbuf.c "add_transp_matindex", and you
replace this with
"add_transp_obindex".

3)
In this commit you also use shi->mat->index when it's shi->vlr->mat->index.

I have done the changes here (I apply the old patch) and is working fine.
