Set Contents with Curve lets you use a curve to define where contents are added to a fluid container. Like a painted fluid stroke, the curve does not emit the fluid but instead inserts fluid samples into the fluid container. When setting fluid contents from a curve, the container’s fluid Content Methods must be set to dynamic or static. See Create dynamic fluid effects or Create non-dynamic fluid effects.
To add fluid contents with a curve
See Draw curves in the NURBS Modeling guide.
You must set the initial state of your fluid to retain the contents added to your fluid container by the curve.
