Maya .mb file corrupted

Hi, 

 

Yesterday night I saved a mb file in maya 2022, everything was ok, no problems...

Today I loaded the scene, no shaders, no layers, some geometry missing, all geometry looks green, what happened?

When I load the file get this message  for each shader or layer name

// Warning: line 0: swatches file depend node not found, icon discarded: name of the shader/layer //

Any ideas??, 2 days of work lost!!

 

Thank´s in advance

 

Juan Carlos

Do you have a back up file?

Yes, I have a backup from two days ago..., I'm redoing all the work today, but I'm very concerned about the origin and cause of the corruption of the file, I ask myself questions as Why this happened?, could happen again randomly?, is a Maya version related error?,  is a redshift related error?, perhaps is a corrupted geometry I imported in the scene?...

 

that´s the question...

Usually this happens when the file is saved with history.

It sounds like an incomplete file, if it's missing things like shader connections.  There's probably no way of knowing what happened from the information available, but some suggestions:

 

- Always save as .MA, not .MB.  It's slightly slower to save and load, but it's easier to recover and troubleshoot if something goes wrong.

- Always increment and save.  Either save with Ctrl-Alt-S, or if you want to do this by default you can check "Incremental Save" in the save options box.  Your last backup should never be two days of work old--this gives you backups constantly, every time you save.  This helps recover from problems, and can also help track down what you were doing at the time that might have triggered a problem.
