in the shot itself. You have to be creative. The important thing is to get the shot you're after. Nobody sees what
goes on before and after the shot or outside the boundaries of the camera.
In this section, you will look at a few examples of fluid setups and see how to get the results shown. When
dealing with fluids, there are few absolutes, and the settings you use will depend very much on the specifics of
your own shot. These aren't step-by-step tutorials but rather a broad look at how specific projects can be ap-

the parameters on your own work, you won't be fiddling blindly.
Bottle of Pop
The image you saw previously in

required considerably high resolution, because of the very literal
bottleneck preventing the fluid from flowing freely at lower resolutions. In this case, the minimal resolution
enabling me to accomplish the effect was 335, which consumed 3 gigabytes of RAM. At lower resolutions, the
voxels were simply too large to recognize the small opening.
The bottle's mesh is shown in
Figure 7-49
. It's a simple model, and the material is a standard glass material.
