Gathering DR Logs

How to gather the distributed rendering logs:

  1. Run distributed rendering and wait for the issue/error message to appear. 
  2. On any (or all) of the faulty nodes: open the Corona Renderer DrServer window and click on each of the log names at the bottom of it (DR Log, Max Log, Corona Log).

  3. Save each of the logs in a desired location.

  4. Send them to us - it is best to compress them together using .zip, .rar, .7z or similar file format.

  5. It may be also helpful to provide Autodesk Backburner logs. Here is how to do it: How to find and analyze your Backburner error logs

We will analyze the log files and then inform you about our findings and possible solutions.


In case the logs cannot be accessed from the DrServer app (for example "access denied" message appears), you can find them in the below folders and copy them to some other place:

  • DrLog.txt - C:\Users\_username_\AppData\Local\CoronaRenderer\DrData
  • CoronaMax2020_log.txt - C:\Users\_username_\AppData\Local\Autodesk\3dsMax\2020 - 64bit\ENU\en-US\plugfg\corona\
  • Max.log - C:\Users\_username_\AppData\Local\Autodesk\3dsMax\2020 - 64bit\ENU\Network
  • backburnerServer.log and backburner.log - C:\Users\_username_\AppData\Local\backburner
