2023.2 Broke my scene

[ehren.addis]

Updated to .2 and now I can not load a scene.  The CPU pegs at almost 100% usage and it freezes opening it.  I can merge some objects, but not all of them.  There wasn't anything special about those objects.  Uninstalled and reinstalled max 2023.1 and everything works as expected.  Please allow for a dot release uninstaller if they're going to fail this spectacularly.

No bueno.

Dang...... I'm now regretting installing this update...... I am trying to open a simple scene I'm working on (nothing at all big, we're talking about a small 5mb scene file.... and it won't open......it stays stuck at 73% open (finalizing load).

How does Autodesk manage it???????

[JezEmin]

On the face of it, it seems to me that scene files which were created using 2023 are the ones I cannot open.  I can open older scene files created using 2019, 2022 etc.......

I confirm the issue. Same here.

[JezEmin]

PLEASE CAN AUTODESK FIX THIS ASAP - I DO NOT WANT TO UNINSTALL AND REINSTALL MY SOFTWARE BECAUSE YOUR UPDATE IS BROKEN.

[Grace.Tevlin]

Same issue here.

Hello @Grace.Tevlin , @ehren.addis and @JezEmin,

Thank you for reaching out to us.  Can you share your scenes with us?  Do you use Chamfer in the scenes that cannot open?

Sorry for this inconvenience.

Hi @ehren.addis @Grace.Tevlin @JezEmin @faiktofur 

We suspect the issue might be cause by Edit or Editable Poly chamfer, can you confirm if that has been used in your problematic scenes.

Does somebody with the issue can share a scene that we could investigate with? (can PM privately)

[fpatry]

Same problem here. Just lost an hour of trying to figure the problem. I'm so sick of that ****...

Now how do I revert to 2023.1?

[JezEmin]

@DanielCantin ,

Highly likely that I did use Chamfer in Edit Poly, though often I use the Chamfer modifier.  But, yes, it wouldn't surprise me if Chamfer in Edit Poly has been used.

Please fix ASAP, thank you 🙂

We received a problematic Max scene from another post, we are looking at it: URGENT - 2023.2 update cannot open scenes created previous 2023 version?

We also have a customer that is confirming our suspicions: 

Chamfering any edge on an open mesh causes 3Ds Max 2023.2 to hang up and load CPU to 100%
specifically when the chamfering edge is touching the border of a open mesh.

Sorry for the inconveniences, we are looking at the issue.

[ehren.addis]

Awesome.  I've been away from my desk.  I could merge objects until reaching one that was an edit spline and edit poly in the stack from the previous version of the app.  Then it would hang.  Yes, I'm sure I used the chamfer in that edit poly modifier.

On behalf of the 3ds Max team I wanted to share with you that we are aware of an issue that is preventing some scenes and mesh data from loading into the recently released 2023.2 update. We are all as disappointed by this issue as everyone else is, we care deeply about 3ds Max and about you as a customer and the expressive content that you create in 3ds Max to tell creative stories.

Thanks to the help and support of the 3ds max community we have received numerous sample scenes, have tracked down what is causing the issue, and are working on a solution that we can deliver out to the world soon so that you can have confidence and enjoyment in 3ds Max 2023.2. We thank you for your patience and support.

Perhaps if you tested your updates a bit more.

The only use I have for Max is the auto retopo tool.

Because I dont enjoy trying to select edges on a weapon mesh with 140k verts, trying set to edges to hard.

Its just so slow....

I'm experiencing the scene hang up today.  My urgent working files would hang up at 69 to 73% and not open.  FIX it now!!!

This is wasting time I DO NOT HAVE.  I am missing my deadline today and client is not pleased.

You can roll back to 3ds max 2023.1 from 2023.2, just uninstalling only 3ds max and install 2023.1 again. All installed plugins and scripts will be fine. It helped me.

[billnuttall]

I can confirm the problem is the Chamfer modifier. Spent two dayings banging my head against the wall on this. As soon as I turned it off (didn't even need to delete it from the stack), the file opened.

[logan_foster_adsk]

I am pleased to share that an update to 3ds Max, version 2023.2.2, is now available to download through the Autodesk Desktop App (ADA) or through the manage.autodesk.com download portal. This update resolves an issue with Chamfer operations in 3ds Max 2023.2 which resulted in the software entering an endless loop and becoming unresponsive either when loading files (locking up at 73% load) or when applying a Chamfer (through the Chamfer modifier, or Editable Poly or the Edit Poly modifier) to edges that connected to an open edge on your mesh data when using “Limit Effect”.

On behalf of the 3ds Max team I would like to thank everyone who took the time to share their scenes and report this issue to us, your help enabled us to quickly confirm and resolve the issue.

I would also like to take another opportunity to apologize for this issue. We are all as deeply disappointed as you are that this issue shipped with 2023.2, and we hope that with 2023.2.2, and future releases of 3ds Max, will resume the positive trend of releases that provided the stability, features, and functionality that assists you to create expressive content and share creative experiences in your work.

I hope you are well and that you can share what you have been working on sometime!

Many thanks!
