So I have just discovered dynamic hair and have been having a marvelous time adding hair to everything - a dog, a cat... a car... eyeballs. Anyhow you get the idea.

But the issue I am having is that when I go back to the assembly room and try to pose anything, the pc goes into a series of calculating hair exercises everytime I try and do anything. It is making posing very slow indeed, as when anything moves, even a tiny bit, I have to wait 4 or 5 seconds while it does it's recalculation dance.

Is there any way to disable this in the assembly room? How can I calculate the hair only once when I am ready to render?

Any help would be appreciated.
