Cannot read EXR, or the file does not correspond to the current VFB

This message means that you are trying to open an invalid file using the resume render feature. When EXR file cannot be read, rendering will be canceled.

Possible causes:

  • EXR file is damaged or inaccessible
  • EXR file was saved with different set of render elements
  • EXR file was saved with different internal resolution setting
  • EXR file was not saved using “Save VFB” feature in resume render section
  • EXR file was stored at different resolution than the currently set output resolution
  • EXR file that was saved was rendered using Region/Crop feature that was changed or disabled later on


  • Rendering should be resumed only if the scene appearance did not change
  • Rendering can be resumed only from Corona EXR files saved using "Save VFB..." button, not from any regular EXR files
  • Rendering can be resumed only if rendering resolution, render elements, internal resolution multiplier and Region/Crop parameters were not changed
