Set Contents with Curve

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

1. Create a 2D or 3D fluid container with or without an emitter.

   See Create a fluid containers with emitters.

2. Draw a curve within the fluid container.

   See Draw curves in the NURBS Modeling guide.

   Note:

   If the curve extends past the boundaries of the container, fluid contents are added to the container only where the curve is within its boundaries, and the number of fluid samples are calculated for the entire curve.

3. Select the curve and the fluid container, and then select Fluids > Add/Edit Contents > With Curve > .

   The Set Fluid Contents From Curve Options window appears.

4. Set the options for the fluid contents that are placed in the container by the curve. See Add Fluid Contents With Curves Options.
5. Click one of the following:
   • Choose Apply and Close to apply the defined fluid settings to the fluid contents that are inserted by the curve. The Set Fluid Contents From Curve Options window closes.
   • Choose Apply to apply the defined fluid settings to the fluid contents that are inserted by the curve. The Set Fluid Contents From Curve Options window remains open.
   • Choose Close to disregard any additions or changes to the fluid settings. The Set Fluid Contents From Curve Options window closes.
6. Set the initial state of your fluid. See Set the initial state of a fluid.

   You must set the initial state of your fluid to retain the contents added to your fluid container by the curve.

   Note:

   You now have the option to delete the curve. This will not affect the contents of the container.
