In this example AWS Deadline with Linux is used. The concept however applies to every other render farm manager as well.

Follow these steps
create shared resources folder on the server
add environment variable DASELEMENT_RESOURCES to point to that shared folder
add pre & post render hooks (needed for the job dependencies)
adjust transcoding templates
copy and paste the "executable" and "parameters" from the example files
can be found on the top of each Python files
add new
Path Valuesfor thewidthandheight

Python hooks
For each transcoding task, the Python hook for ‘pre_render’ (pre_render.py) and ‘post render' (post_render.py) gets the Job ID from the render farm. If the main task isn’t finished then there is nothing to render for the proxy tasks and they will probably fail.
...

Post Render Hook
The input is the output of the process called by the custom command task.
