Emit fluid properties into grids

You can add fluid properties (Density, Temperature, Fuel, and Color) to a fluid container using a fluid emitter. A fluid emitter creates fluid property values and modifies the voxels of a grid with the values as a simulation plays. The fluid emitter must be within the bounds of the fluid container to emit.

When you emit fluid properties into a Dynamic Grid, Maya creates the property values and solves them to create the fluid motion.

When you emit fluid properties into a Static Grid, Maya creates the property values, but no solving takes place so only the voxels within the emitter Max Distance range are populated.

You can:

• Emit from multiple fluid emitters in a container.
• Remove Density, Heat, and Fuel from a fluid container using a fluid emitter with negative emission values.
• Keyframe the fluid emitter position within the container the same as for any other object. See Set keys for information on setting keys.
• Emit speed properties into a fluid container. See Emission Speed Attributes.
• Emit fluid properties into a container using a 2D texture emission map. See Emit fluids using emission maps.
• Emit fluid from an object surface. See Emit fluids from objects.
• Fill selected geometry volumes with fluid. See Fill geometry with fluid.
• Emit fluid from an nParticle object. See Emit fluid properties with nParticles.

For information on emitting Color into a container, see Add color to fluids.
