Enable 'Auto-Convert Textures to TX Files' might be the cause of render errors in render farm (for Arnold 5 or later).
Therefore, if using Arnold 5 or later, you will need to disable 'Auto-Convert Textures to TX Files'. This will prevent errors with your output files.
Below are details: from your render setting
- Disable the 'Auto-Convert Textures to TX Files' option
- If you are using TX Textures, please enable the 'Use Existing TX Textures' option (make sure you converted TX Textures via your computer and upload packaged them within your Maya project)
Now, upload your scene and related assets to our render farm
