Missing geometry after saving

[coeuscreative]

Hi,

Sometimes when open a file a lot of the geometry is missing. See attached file (for maya 2020)

(Seems like I can't even post the file. When I try to this forum gives me the following error.
The attachment's yetanotherfatalbug.0006.ma content type (application/octet-stream) does not match its file extension and has been removed.)

There seem to be two solutions.

If I set one of the construction nodes states to "Has no effect" the geometry reappears. If I delete the history while the geometry is invisible it's gone forever. (painful experience)
Or if I delete the joints and resave the scene. (Not that the object is skinned to the joints)

Try to post file via zip

Hi Terrance, please search the Forum for missing geometry or corrupted file, there are many posts just like yours.

Good luck.

Thanks I did that already, but nothing seems to map onto what I'm seeing particularly acurately.

Try  to pick up work from a previous saved file from your incremental saves, that’s all I can see in your scene, avoid saving the scene with history. 
your scene is very small, I recommend working in real world scale.

Thanks, yeah, I can go back and find an uncorrupted file....

Problem is, this is happening when saving/loading. So there's no way to tell when this happens, unless you reopen the previously saved version in another instance of maya to check that its not corrupted before closing the unsaved scene.

Which isn't really a great way of working.

Plus it makes Autosave a usless feature.

I've been using Maya for a while and I've never seen this in previous versions (up to 2014). It feels like a serious bug.

Just try to clean up the file next time before saving. 
I’ve tried to edit the file but to no avail.

What do you mean...

As I said in the original post
" If I delete the history while the geometry is invisible it's gone forever."

but

"If I set one of the construction nodes states to "Has no effect" the geometry reappears."
So it is fixable, but as I said, it makes autosave effectively incompatible with construction history.

Also what did you mean earlier that the model is too small. It's 14 cm high. Are you saying that Maya can't cope with models smaller than 14cm these days?

[damaggio]

No, I'm using 2019 and deleted the history in the scene and everything is fine.the model is there as seen in my picture.{ but i don't know how the model was before}

I don't know what this is but I thought it was an animal so I was suggesting a larger scale, if the modeling is working for you than just ignore.

I just always work in real scale, that's all.

I tried to edit the file in Wordpad but it didnt work.

Also, while is important to test a fresh new Maya version to discover any bugs I would never do serious or client work on a new Maya version, specially during production, I wait until the first update.

Hi!

Here the scene can be opened and the object "MISSING_OBJECT" is visible.

Do you get any error or warning messages in Script Editor Output, when loading the scene?

It was the 3d mouse drivers.
I have a 3dconnexion space explorer. Somehow, the latest driver seems to be causing the effect I described above.

I can't imagine why or how a 3dmouse driver would cause  an object with history nodes to fail in the scene. But there we have it, I uninstalled that driver and the problem has gone away.

I found a post from a couple of years ago where xomeone described a similar issue, but only when using Redshift. I use Vray, so maybe the issue isn't the renderer. Just the mouse driver.

Happy you found the solution. 
maybe you could switch to a Wacom intuos tablet, they work really well for painting and sculpting.Cheers

Thanks, but a 3d mouse is a very different thing.

I've got an intuos and a cintiq(knock off). Those are effectivly replacements for the mouse.

A 3d mouse is actually a dedicated device for navigating in the viewport. It replaces the alt-mouse movement controls that orbit/pan/dolly the camera, with a multi axis joystick which allows you to intuitively fly around the scene.

It's great when it doesn't destroy the geometry in your scene...
