User Manual

 Particle Age: Each particle animates through the sequence of images provided by
the Style Bitmap node, independently of other particles. In other words, an individual
particle’s appearance is taken from the Style Bitmap node at successive times, indexed
by its age.
 Particle Birth Time: New particles take the image from the Style Bitmap node at
the current time and keep it unchanged until the end of the particle’s lifespan. Thus,
particles generated on a given frame will all have the same appearance and will stay
that way.
Time Offset (Bitmap Style)
This control allows the Bitmap source frame to be offset in time from the current frame.
Time Scale (Bitmap Style)
This control scales the time range of the source bitmap images by a specified amount. For
example, a scale of 2 will cause the particle created at frame 1 to be read from the bitmap
source at frame 2.
Gain (Bitmap and Brush Style)
This control applies a gain correction to the image used as the bitmap. Higher values produce a
brighter image, whereas lower values reduce both the brightness and the transparency of
the image.
Style Bitmap (Bitmap Style)
This control appears when the Bitmap style is selected, along with an orange Style Bitmap input
on the node’s icon in the Node view. Connect a 2D node to this input to provide images to be
used for the particles. You can do this on the Node view, or you may drag and drop the image
source node onto the Style Bitmap control from the Node Editor or Timeline, or right-click on
the control and select the desired source from the Connect To menu.
Brush (Brush Style)
This menu shows the names of any image files stored in the Brushes directory. The location of
the Brushes directory is defined in the Preferences dialog, under Path Maps. The default is the
Brushes subdirectory within Fusion’s install folder. If no images are in this directory, the only
option in the menu will be None, and no particles will be rendered.
Noise (Blob Style)
Increasing this control’s value will introduce grain-type noise to the blobby particle.
Fade (Line Style)
The Fade control adjusts the falloff over the line particle’s length.
The default value of 1.0 causes the line to fade out completely by the end of the length.
