7.
In the Options group, turn on Split Scan Lines,
and then click Define.
The Strips Setup dialog appears. The dialog
displays the output resolution, and lets you
determine how to split up the rendering job by
specifying the number of horizontal strips into
which the image will be subdivided.
8. Specify the vertical size of each strip in pixels
or as a percentage of the total image height, or
set the number of str ips. Changing one also
changes the other.
9. Set the overlap in pixels or as a percentage.
Using overlap isn’t always necessary, but if
you notice anomalies where the str ips meet,
increase this value.
10. Connect to the manager, specify a job name,
choose one or more servers on which to render,
and then click Submit.
The job is sent to the network rendering
manager, which supervises the network
rendering job. The job consists of first
rendering each slice, and then combining, or
“stitching,” the slices into the final image.
11. Monitor the job via the monitor.
Rendering and stitching passes are designated
“Slice Pass” and “Stitch Pass,” respectively.
When all slices are finished, the job status will
be Complete.

Default=10 p ercent of the total image height, in
pixels.
This setting is interdependent with and inversely
propor tional to the Number Of Strips setting;
increase one, and the software decreases t he other.
Number of S tr ips —Sets the number of horizontal
strips to be rendered by the available servers.
Default=10.

machines to which the job can be farmed out. For
example, if you use the default setting of 10 strips,
the job can be performed by 10 machines at most.
In that case, assuming equal performance of all 10,
rendering would take approximately one-tenth the
time required by one machine.
Tip: Foroptimalresultswithrenderfarmsthat
comprise machines of different speeds, use a value
high enough that the job can be completed most
