The Strips Setup dialog
lets you specify how to split up the rendering of a single, large
image among several different servers on the network. 3ds Max automatically
subdivides the rendering based on settings you provide, and then
fits the pieces together into the final image.
NoteA version of this
feature was known as Region Net Render in versions of 3ds Max prior
to version 8.
To render a large image with a networked
- Set up a scene to render.
- Set up your system for
- From the Rendering menu, choose Render
The Render Setup dialog
opens, with the Common tab active.
- In the Output Size group, specify the
size to render.
- In the Render Output group, specify an
output file name and location, and turn on Net Render.
- Click the Render button.
The Network Job Assignment dialog appears.
- 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.
- Specify the vertical size of each strip
in pixels or as a percentage of the total image height, or set the
number of strips. Changing one also changes the other.
- Set the overlap in pixels or as a percentage.
Using overlap isn't always necessary, but if
you notice anomalies where the strips meet, increase this value.
- Connect to the manager, specify a job
name, choose one or more servers on which to render, and then click
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.
- Monitor the job via the Backburner Monitor.
See “Monitoring and Managing Jobs” in the Autodesk Backburner User’s Guide.
Rendering and stitching passes are designated
“Slice Pass” and “Stitch Pass,” respectively. When all slices are
finished, the job status will be Complete.
- Output Resolution
This read-only field displays
the horizontal and vertical resolution of the final image, in pixels.
- Strip Height
Sets the height of each horizontal
strip in pixels or as a percentage of the total height. Default=10
percent of the total image height, in pixels.
This setting is interdependent
with and inversely proportional to the Number Of Strips setting;
increase one, and 3ds Max decreases the other.
- Number of Strips
Sets the number of horizontal
strips to be rendered by the available servers. Default=10.
The value determines
the maximum number of 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.
TipFor optimal results
with render farms that comprise machines of different speeds, use
a value high enough that the job can be completed most efficiently.
For example, consider a two-server network with one machine four
times as fast as the other. If you set Number Of Strips to 2, the
job won't be finished until the slower machine renders its half
of the final image. But if you set Number Of Strips to 4, the faster
machine can render three of the strips while the slower machine
renders one, effectively halving the total render time.
This setting is interdependent
with and inversely proportional to the Strip Height setting; increase
one, and 3ds Max decreases the other.
Set the amount by which each
strip overlaps the adjoining one(s). You can set this in pixels
or as a percentage of the final image height.
A certain amount of overlap
is necessary to compensate for image artifacts created by antialiasing
and render effects. If you notice anomalies where the image slices
meet, try increasing the Overlap setting.
Determines whether the Strip
Height and Overlap settings represent pixels or a percentage of
the final image height. Choosing a different option automatically changes
the two values accordingly.
- Delete Temporary Images Upon Completion
Deletes the “slice” images after
the final image is created. Default=off.
