Render Mode
By using PyroCluster as a post effect (VideoPost) you can often cut render times
dramatically. When VideoPost is selected, a simplified rendering process is used,
which among other things handles fractals differently. This means that you will get
a different result when using VideoPost than you would with Atmospheric mode.
dramatically. When VideoPost is selected, a simplified rendering process is used,
which among other things handles fractals differently. This means that you will get
a different result when using VideoPost than you would with Atmospheric mode.
For better and faster results with VideoPost, turn off particle shadows using the
relevant options on the Shadow page. If you leave particle shadows on, there may
be little or no increase in render speed. Note that, in general, VideoPost rendering is
faster only if you are using a large number of particles.

The limitations of the VideoPost mode are that fractals look different, particles cannot
be seen in reflections or behind transparent objects and Flat Radius mode is always
used, regardless of the Gradient Mode selected.

Preview
Some examples of using the
PyroCluster preview, illustrating the
use of the background option and
the age slider. Changes to settings
will be shown instantly in the
preview, which uses shadow casting
lights to represent the effects as
accurately as possible.
Once you are familiar with PyroCluster you’ll find that it is not always easy to predict
how the various options will affect the final result. Fractal volume calculation is highly
complex and the interdependencies are limitless; the color of one point in the volume
may be affected by hundreds or even thousands of other points in the volume.

PyroCluster is simulating natural phenomena and, as in nature, things like clouds
and fluid movements are often chaotic and unpredictable. It would all be too hard
if there wasn’t a hint as to how PyroCluster effects will render; this is where the
PyroCluster preview comes in.

Enable the floating PyroCluster Preview window by clicking the Preview button on the
Globals page. This window will render a single puff using all settings. A live connection
between the settings and the preview means that any change to the settings will
automatically be reflected in the preview. The preview window uses shadow casting
lights to render the puff as accurately as possible.

The PyroCluster preview has a number of options. You can toggle between a checkered
pattern background (with a transparent puff) and a solid, colored background by clicking
the checkered icon. You can change the color of the solid background by clicking on the
icon beneath the checkered icon. By dragging the slider at the bottom of the display,
you can update the display to show how the puff changes over its lifetime.
