Possible Causes:

The error typically arises from corruption within certain elements of your 3ds Max scene, leading Backburner to either fail or restart the rendering process after each frame.

Proposed Solutions:

Here are some troubleshooting steps you can take:

  1. Start with a fresh, empty 3ds Max scene.
  2. Navigate to File and select Import.
  3. Choose Merge to bring in the problematic scene elements, including your current render settings, into the new, clean 3ds Max workspace.
  4. Save the new scene under a different name, then resubmit it for network rendering.

Another approach involves copying the Maxadapter.adp file, found in C:/Program Files/Autodesk/, from the Manager PC to the Server PC. After doing that, try a test render.
