You can emit fluid from any polygon or NURBS surface that is inside a fluid container. The fluid emits from the surface towards the closest voxels.

For closed objects (for example, spheres), the fluid emits from the external surface only, which means you cannot emit into the object using this technique. (You could emit into an object using a volume or omni fluid emitter.)

To create a fluid by emitting from an object into a fluid volume

1. Create a container.

   See Fluid containers.

2. Create the polygon or NURBS object you want to emit fluids.
3. Move the object or container so that the object is completely inside the fluid container. (An object can emit fluid only when it is inside a fluid container.)
4. Select both the object and the container.
5. Select Fluid Effects > Add/Edit Contents > Emit from Object. Maya creates a surface fluid emitter and connects it to the object and the fluid container.
6. Modify emitter attributes as appropriate. For details, see Modify fluid attributes.
7. Modify fluid attributes as appropriate. For details, see fluidEmitter.
