How do I build half/half shells?

A half/half-shell in FWsim.A half/half-shell in FWsim.

In the effect editor, click "File" -> "New". Select "Peony". Add a second set of Stars to the explosion node. Give each of the stars a different color. Set the distribution on both stars to "Hemisphere". Then, click one of the stars and check "Rotate", enter "180". Be sure to rotate only one of the stars, and not the other. Your effect tree should look like this:
		Stars (Green, Rotate by 180�)
		Stars (Red, no rotation)
To make the shell look a bit more clean and perfect, reduce the "speed variance" and increase the star count in both "Star" nodes.
