Opening UV Editor Crashes Max 2021

[Nick.Pazdan]

Only reference I can find from a similar issues on the forums is a 9-year-old post. Applying an Unwrap UVW modifier to any object in 2021 and trying to open the UV Editor from the subsequent menu results in a "Sorry an error has occurred and the program will now close" message. It happens with existing and new scenes. This behavior is not present on a 2019 install of Max. 

I have VRay, Substance, Floor Generator, and Itoo's set of free plugins installed, but otherwise this is a fresh install of Max on a Windows 10 rig. Any ideas on possible solutions? I was doing a test run with 2021 to justify updating our studio to the latest version but UV's are a pretty critical part of the workflow.

Hi @Anonymous,

If you still have both sets of ENU folders -- the "old/bad" one and the newly-created "good" one -- I could very much like to get zipped copies of both folders to send to our developers so we can analyze exactly what's going on here.

If you want, please send me a private message and I'll send your a OneDrive link where you can upload them. Thanks, and I hope to hear from you soon!

Hi everyone,

I just wanted to note that the defect # we have for this is MAXX-57413, so please refer to that if you want to check on its status.

Although I can't give an exact release date on a fix, this issue has been looked at and addressed by our developers, so I'm hoping we can pass along some good news to everyone in the not-too-distant future. Thanks for everyone's patience on this!

Hi, I'm sorry but Is it so difficult to reverse engineer what is going on? It's been months now and a Service Pack later and still not resolved?

3ds Max 2021.3 features a fix to the issue with the Vray default material not interfacing with the Checkeredmaterial because it doesn't contain a subtexmap. As such I would recommend that you update to 2021.3 or contact Vray about their materials are doing.

Hello @Anonymous ,

This issue was reported as fixed in Update 3 for 3ds Max 2021.

Could you please log into your Autodesk Account and make sure you've downloaded and installed the 2021.3 update?

Please let us know if this helps!

sorry for this basic question: I only need to install  the latest update? 2021.3 - and not 2021.2 2021.1... ?

[logan_foster_adsk]

You can install 2021.3 directly, it will contain everything in the other updates (in fact it is a complete new install of 3ds Max)

Hi

To solve this problem, you do not need to remove any plugins, just set the UI to the default mode and return from vray mode to max mode: customize <custom defult switcher

If there are several updates, i only need the 3.5 update, or should i install all of them? (1.2, 2.2, 3.5)?

[Anonymous]

Where can i find out, which updates i already installed?

[keith112]

3.5 contains all of 1.2,2.2 etc

Hi guys! I am having the same problem. Did anyone solve it?

[JeanNelson4926]

We understand what you saying but who wants to switch the whole time back and forth so that one can use the unwrap feature when one works with vray materials...

[JeanNelson4926]

seems to be fixed now ..at last
