Chaos Corona for 3ds Max => [Max] Bug Reporting => Topic started by: gmh_2001 on 2024-07-03, 20:02:15

Unfortunately this version (12) has totalled my 3dsmax 2024 -UI crashes every time on startup. What gives?
-
Hi,
Sorry to hear that. Does 3ds Max load and then crash or it does not load at all?
In such cases, doing a ENU reset is a known possible solution:

Please try this and let us know if it gets solved.

It loads and then crashes. I've gone back to Corona 11 and it's fine now.
-
Just installed Corona 12 on Max 2025 and it also crashes 3Ds max when clicking Start Virtual Frame Buffer.
Shocking, but true.
-
Have also problem after installation 12 corona
-
I think my problem is very similar or with a common cause: every time I want to reset my Max window, it crashes in the same way.
-
Hi,
I also had a crash (still have the minidump) when using it for the first time. I think what I did was just deleting the SystemSettings config file(s) of Corona. So maybe try to delete (make backup if you like) all files in
ENU\en-US\plugcfg\corona
Good Luck

This did not help in my case.

yup this is happening to me also.
some scene files are ok others it crashes exactly as per your screenshot.
always during render time.
-
Yeah I've wasted an entire afternoon now stripping everything out and reinstalling and I'm still getting this UI crash -new gpu driver everything. I'm beyond disappointed.
-
I experienced kong delays using IR. Also when loading corona tile in the SM 3ds max crashed. Have to reinstall corona 11 agian

Nope. Resetting max didn't solve the problem. I've done a bunch of troubleshooting, which included doing a clean install of Max and removing all related folders (including those in registry)
Updated system bios and graphics card drivers to the latest.
Installed corona 12 only without other plugins. And max just shows an application error window on launch and crashes.
The first crash report I got after all these steps points to CoronaUi_Release.dll
Subsequent crashes just pointed to 3dsmax.
Max version is 2024.2.1

Please try getting the minidump and send it over. Here is how to do it:

Waiting now for Hot Fix 1

Waiting now for Hot Fix 1
Did you submit the crash report, I haven't gotten to doing this yet cos I've been busy, hopefully, hotfix 1 fixes everything.
-
Dear users,
Hotfix or any release may fix an issue by a chance, but it most probably won't if the issue is not clear and is not duely reported.
The best report include a screen recording of everything being done, scene if present, and the minidump.
Collect those if you can and submit it through:

I had to uninstall and install corona 11 h2 immediately -I'm running a business not a beta tester sorry. If I wanted to mess around I would have installed a daily. Corona release 12 should be a finished product -that's what I pay my subscription for. No? I'm not running anything unusual, Threadripper, 4090, installed under admin account on Win 10. Should be good to go. It broke my whole interface!
-
Crashing here too, when i hit IR before the render starts... Went back to 11.
-
I can understand your frustration, but please note that:
- Every Corona release undergoes multiple tests (by our devs, QA, support teams, other teams, both automated and manual)
- Corona 12 does not crash on our office machines (various hardware and software configurations, Intel, AMD, desktops, laptops), and I am not aware of any surge of crash reports during the daily build / RC phase, so the problem is not global, it's most likely system-specific
- If anything is working wrong for you (crashes or anything else), please contact us at https://support.chaos.com/hc/en-us/requests/new - otherwise we won't know what the problem is so we won't be able to provide a fix

corona render node crashing, won't render. Reverted to 11
I won't vent my frustration in ranting, it's useless. But everyone who said they expect a finished product for their money, is correct.
There's no excuses. Corona 12 is not a finished product.
And we are all working with deadlines; don't release it as such, cause I for one do not download any new version until it's out for public download as a finished product. You cost me 4 houres of bullshit on installing and finding out it's unstable.
-
I have a 13900K
It seems to be a Intel CPU problem.
I tweaked the maximum temperature of the CPU to 85º Celsius and Corona stopped crashing
Maybe with 90º would be sufficient, have to try.

Corona 12 h1 still broken for me had to downgrade again!!! I will wait now until I install windows 24h1.

Same here. I've given up and reverted to 11.2, what has windows 24H1 got to do with the installer crashing max?
-
It will give me a chance to rebuild 3ds max with a fresh install so I can see where the conflict is coming in. Can't believe it would be my hardware..3970x...4090..It could be that Corona is fighting with a plugin, driver or env variable..don't know. Just annoying that it's so sensitive..Vray Arnold etc work fine!

Im noticing crashes running interactive with an object that uses a path deform modifier. If I disable or remove the object using path deform I dont crash.
-
Hey, had similar issue, when corona 12 either not rendering or crashed in IR render. In my case - in one of the scenes, I had corona scatter with edge trimming enabled on the chaos scatter rollout. And one of the instanced object that was used for scattering had edge trimming map in opacity slot. Even tho it was disabled in material, it still would crash. Once I've removed the map - it started to render without the problem.
In 2nd scene I as well had chaos scatters, tho I did not had time to check if any of the scatter objects had trimming map, removing chaos scatter for good helped.
UPDATE:
In 3rd scene, I did not had any scattering at all. The scene crashed as soon as I've opened material editor or started IR render

Both of these cases will be worth to investigate, and seems you did great work identifying where the issues may be.
Please, if possible, submit the scenes (or trimmed down versions of them) for us to have a look. Thanks.

Stupid question, how and where do I upload the scene?

You can submit a new ticket at: https://support.chaos.com/hc/en-us/requests/new
and attache the scene.
You can also specify this forum thread in the ticket to keep better track of things.

Done!
Another thing that I've noticed regarding chaos scatter. If I open the scene with scatter present ( edge trimming turned on in the roll out ) and start rendering: If I'm rendering in IR mode, It crashes, In normal render it stucks in parsing mode, with max render windows missing at all.
Then, if I turn edge trimming off and on, it will render normally in both modes.

This can be yet another very good finding!
If that is the case for the scene you have attached, feel free to add that information in the ticket too (if you have not done it yet).
Support guys will process it further for QA.
Thanks.

Just a quick question for you since our issue is typically the same ( Corona 12 crashes max on launch after installing it), do you have Memory Integrity turned on or off under core isolation for windows 11? could it be possible that windows is somehow blocking the .dll file for corona, i once experienced this in some certain older versions of 3dsmax and had to turn that setting off.
I haven't tried reinstalling corona HF1 after disabling this windows setting. All the other suggestions from corona support did not work as well.
