Thanks guys it's late but I'll try that out tomorrow.

And I'll post my setting etc then too.

The hair is not duplicated it is loaded directly from the library, but there are two of them.

I use two so that all the hair doesn't have to move in the same direction at the same time.  Both are parented to the head.

I'm pretty sure that it works the same with only one, but I'll check that tomorrow too.

As I said I once had a problem where a bird that flew behind my character's head flew through the hair no matter how far behind it was.

It wasn't an illusion; you could see it enter the hair about half way back from the front when viewed from the front even when it was 10 feet behind the figure.

I never did figure that one out.

If you shoot a mime, do you need a silencer?
