Grassy Field Tut Question


I took Kirupa’s tutorial on how to make a grassy field (which can be found HERE and it worked out. But now I have a different problem:

I need to get all those grassy blades out of my movie at a sudden point. They just need to go, but I can’t figure out how to. I tried multiple things:

  • Masking the layer doesn’t work
  • Creating a new layer on top of them all, and putting a black square on that one, which covers everything, doesn’t work either
  • Changing the alpha of the first blade…nope.

So maybe it’s a code thing? Does anyone of you guys have an idea?

Thanks in advance and merry Christmas :?)
