I’m having problems making the z-depth or mist pass, because they don’t take care of z-transp materials. and for my scene is necessary because is plenty of grass and trees with leaves.
I have being reading this thread http://blenderartists.org/forum/showthread.php?t=120889 which is really interesting, but even with the solutions proposed I can’t fix it.
I’m be very glad if you could help me, here you have a simple blend file showing the problem.
