To change the size of a fluid container
- Select the fluid container.
- 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.
- A 2D fluid with a depth (Z Size) of 0
will not render as a volume, but you can set the height to 0 (see
Use Height Field)
or surface render (see
Surface Render)
to achieve a reasonable result.
To scale a fluid container
- Select the fluid container.
- 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
- Select the fluid container.
- Select
Fluid Effects > Extend Fluid > or click .
The Extend
Fluid Options window appears.
- 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.
TipYou can shorten the
fluid container boundaries by entering negative numbers.
NoteUsing
Extend
Fluid to change the size of a container is different
than using
Auto Resize.
Extend
Fluid sets the X, Y, and Z
Translate attributes
on the fluid's
Transform node.
Auto
Resize uses the
Dynamic Offset value
to resize the container. See
Set a fluid container to dynamically resize.
