The following were posted by ralphaelninja to Simtropolis in 2004. It appears that this has disappeared from there so I thought it might be useful here.
B.A.T. Export Error Codes
The most common export error is the file-sharing error. Make sure that the Lot Editor or SimCity 4 are not running during B.A.T. export. Both of these applications prevent B.A.T. for writing to the output file.
Here are the explanations of all error codes reported by B.A.T.
Error #0 - Export initialization error. Possible causes:
• Missing cameras and lighting rig.
• Failure to create output file.
Error #1 - Temporary object cleanup error. Possible causes:
• Corrupted file
Error #2 - Error finding/creating LOD shells.
Error #3 - Error writing model info to the output file. Possible causes:
• File sharing violation. This typically happens when the Lot Editor or the game is running.
• Output file is write-protected (read-only).
Error #4 - Error rendering thumbnails. Possible causes:
• Running out of memory.
• OS error.
Error #5 - Error saving thumbnails to the output file. Possible causes:
• File sharing violation. This typically happens when the Lot Editor or the game is running.
• Output file is write-protected (read-only).
The subsequent errors can occur while exporting particular zooms and rotations. They repeat cyclically.
• Errors #6 - #11: zoom 5 rotation 1
• Errors #12 - #17: zoom 5 rotation 2
• Errors #18 - #23: zoom 5 rotation 3
• Errors #24 - #29: zoom 5 rotation 4
• Errors #30 - #35: zoom 4 rotation 1
Error #6 - Error rendering/saving zoom 5 rotation 1 view. Possible causes:
• File sharing violation. This typically happens when the Lot Editor or the game is running.
• Output file is write-protected (read-only).
• Running out of memory.
• OS error.
Error #7 - Error collecting scene nodes for S3D export.
Error #8 - Error rotating export nodes.
Error #9 - Error saving export nodes to the output file. Possible causes:
• File sharing violation. This typically happens when the Lot Editor or the game is running.
• Output file is write-protected (read-only).
• Bad units. Make sure you are using metric system.
Error #10 - Error rotating export nodes.
Error #11 - Error saving export nodes to the output file. Possible causes:
• File sharing violation. This typically happens when the Lot Editor or the game is running.
• Output file is write-protected (read-only).
• Bad units. Make sure you are using metric system.
