My animation modified itself after I copied the scene file

[Anonymous]

I have been working on an animation project for school those past two months, and it is reaching its end. Unfortunately, today, I realized my animation broke. I had to transfer my work files to my laptop since school has opened again, but once I opened my scene on my laptop, I could see the animation was not how I had left it (I had made a playblast in which everything worked fine the day before), so I turned on my desktop to open the original file. To my surprise, the exact same problems where apparent on the file.

I feel like I have lost several days of work and I have no idea why. I have nothing to go from. I didn't do anything apart from copying the file (.mb format) since the last playblast I made and it now is broken.

I might have to re-do the whole animation, but I wanted to post here to see if someone had experienced such a weird problem before.

Thank you in advance.

What is the “problem”?  You need to explain the problem do we can help you.

The keyframes I had put have been modified without me having done anything between the closing and re-opening of the file.

Modified how?

Please be as specific as possible.

Are you sure you saved it before shutting Maya down?

Also make sure your FPS haven’t changed.

Yes I am sure I saved the file. Modified as in "some keyframes' values changed in a seemingly random way without me having done anything about it".

hmmm....

did the frame rate of your environment or scene change?

What frame rate were you working in before? When you open the scene what frame rate is set?

Did you have any file references with edits on them?

When you say you "copied" the file what do you mean by this?

The framerate was 24FPS. When I opened the file on my laptop, the setting in "Time Slider" was "Play Every Frame", which I had to change in order for the animation to play correctly.

I have two references in my scene. Two rigs which are animated. I don't recall having made any modification to them between the closing and re-opening of my scene.

By "copied" I mean I have simply right-clicked on the .mb file and pressed "copy" in order to "paste it" in my USB key.

Make sure your FPS is the way it was before.

That has to be what your problem is.

Copying your file won’t effect it like that.  Unless you opened it on a different machine and the global settings are different.

I have found the solution to my problem! I had modified my referenced files and hid and locked an attribute that was animated, which modified the animation in my scene completely. I have managed to unlock and unhide said attribute and everything has gone back to normal!
