Hi,

I took Kirupa’s tutorial on how to make a grassy field (which can be found [HERE](http://www.kirupa.com/developer/mx/grass.htm) 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 :?)
