Describe the problem
In tile_merge.py, Image.open() and OpenEXR.InputFile() calls have no error
handling. If a tile file is corrupt, missing, or fails to open for any reason, the
script crashes with a cryptic Python traceback that doesn't indicate which tile caused
the failure.
Proposed Solution
Wrap all tile file opens in try/except blocks with clear error messages identifying
which tile index and file path caused the failure:
- Line 48:
Image.open(tile_paths[0]) — first tile open in merge_tiles_pillow()
- Line 63:
Image.open(tile_paths[tile_index]) — tile loop open in merge_tiles_pillow()
- Line 81:
OpenEXR.InputFile(tile_paths[0]) — first tile open in merge_tiles_exr()
- Line 102:
OpenEXR.InputFile(tile_paths[tile_index]) — tile loop open in merge_tiles_exr()
Example Use Cases
- A tile render task failed silently and produced a corrupt output file — merge step
should report exactly which tile failed instead of a generic Python error
- Disk space ran out mid-render leaving a partial tile file — clear error message
helps diagnose the issue quickly
