To change the size of a fluid container

1. Select the fluid container.
2. In the Container Properties section of the fluidShape Attribute Editor, change the Size attribute. When you change the size, keep the following in mind:
   Tip

   • Make the size proportional to the grid resolution, even if you do not use any grids to define property values (that is, you use all gradient style values).

     For example, if the size is 10.0, 5.0, and 2.0, then a valid resolution is 40, 20, and 8. If the size is not proportional to the resolution, the quality of the fluid can vary depending on which axis you look down.

   • When Keep Voxels Square is on, changing the container’s Size attributes automatically scales the Resolution values so that they are proportional to the size. See Keep Voxels Square and Change fluid resolution.
   Note

   A 2D fluid with a depth (Z Size) of 0 will not render properly as a volume.

To scale a fluid container

1. Select the fluid container.
2. Do one of the following:
   • Select the Scale Tool and use the scale manipulator to change the proportions of the fluid container as desired.
   • In the Transform Attributes section of the fluid tab in the Attribute Editor, change the values of Scale X, Y, and Z.

To extend a fluid container

1. Select the fluid container.
2. Select Fluid Effects > Extend Fluid > or click .

   The Extend Fluid Options window appears.

3. In the appropriate fields, enter the number of voxels by which you want to extend the container in each direction and click Apply and Close.
   Tip

   You can shorten the fluid container boundaries by entering negative numbers.
