Crash with OSL wParallax

[vizset]

Hello!

In 3ds Max 2023 with Corona 9 I have stable crashes with OSL wParalllax textures.
I use OSL map on physical material with self-illumination and corona multi-map inside.
In empty scenes OSL works correctly.

Previous version 2020 with Corona 8 works correctly (including huge scenes with the same material), I didn't change any parameters, paths. etc.

I moving the topic to bug reporting board, but please read this article and provide additional material that would help to identify the issue, like minidumps, scenes, assets that's cause the issue.

Yep, we will need the scene itself, or at least specific instructions how to reproduce the crash.
The most convenient way to report the bug and attach your files will be through our support portal - https://support.chaos.com/hc/en-us/requests/new

ive also been having some issues with this i suspect, but seemingly only on my computer in the office. opening many scenes with wParallax the first render renders fine, then if i stop and start a render it crashes 90% of the times if it contains wParallax planes. If i hide the wParallax in the scene it seems to work fine.
Not sure but i think its happening if i have the wParallax material in my material editor visible.

Hi I have tried to reproduce the crash but was unsuccessful, would it be possible to share an archived scene with us that the issue is reproducible? Ideally use: https://support.chaos.com/hc/en-us/articles/4649117083409-How-to-report-issues-3ds-Max- as suggested above. Thanks!

Hi VIZSET and SmurfN, could you please share some more details here and/or submit support tickets about this issue? You can submit tickets here: https://support.chaos.com/hc/en-us/requests/new
As George explained, so far we were unable to reproduce the crash.

Thank you for your response! I sent request #68772, the full file is included.

I have the same problem! 9 times from 10 3ds Max crashes. First render (no matter regular or interactive) is OK. But the next one crashes the 3ds Max.
My colleague has the same problem (his setup: 3ds Max 2023.2 + Corona 9 + Win 10 / my setup: 3ds Max 2023.2.2 + Corona 9 + Win 11).
Everything was fine in the previous versions: 3ds max 2022.2 + Corona 8

Same for me, yesterday I tried to render a simple plane with an evermotion archmaterials 4 texture and 3dsmax crashes inexorably but somewhat randomly (sometimes after the 1st render or sometimes after a few renders). I use the evermotion OSL script (which automates the creation of OSL material)
I'm on max 2023.2.2, win 11 and corona 9.
Thanks a lot

Hi, dev.team,
Could you please help me? OSL parallax is time to time crashes 3ds Max to desktop in different scenarios. Most crashes occur while playing with materials (different, not only with OSL parallax). Could you please check it out to be sure wats wrong with it?

PS
I'm using 3ds Max 2023.2.2 with Corona 9 (there is a lot of information on the Internet about the correct working parallax with 3ds Max 2022 corona 7, unfortunately, I cannot check it out).
I cannot get the 3ds Max minidump file, because crashing won't display this window.

Report #69464

The problem is still repeated on Corona 9 Hotfix 1.

upd.
The team is investigating the scene. Thanks them to all.

[scionik]

some news about it?

[maru]

We were contacted by multiple users, we have at least one scene where the issue is reproduced and a minidump. The issue is reported for the dev/QA teams to investigate. I cannot tell what is wrong right now, but if it's something in Corona, we should be able to fix it. Crashes are high priority for us.
