Crash with OSL wParallax

[scionik]

Thank you

[NikHappy]

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.

I switched back to 3ds Max 2022.3 + Corona 9, and now render launch crashes with OSL are completely gone. So most likely the problem is in 3ds Max 2023, and not in Corona

We still have crashes on Max 2022.3, so I think the issue is still there, either on the plugin side (wParallax) or Corona

For info we have this reported and I'll let you know when we have some more information.

Hello,

Can you please contact hello(at)wparallax.com

We are working on some solutions to this issue, will be good to get some beta testers of new scene setups to check if it still crashes.

Thanks!

I can also confirm, the error occurs in max 2023 and corona9 (also vray6). 
Not sure if it is max problem, renderer problem, or osl (however, osl seems to work fine in previous versions).
I was doing different tests with different material setups, original wparallax material setups use multimaps, I have tried without and it crashes but less ofthen. 

A very strange thing is that wparallax original scene works perfectly fine with alot of constand tweaking and basically pushing everything to the limit, absolutely no crashes occur.  Only when importing the planes into a new project scene, then the crashes might occur, sometimes it works just fine, and other times just randomly crashes.   So, maybe the issue is with Material Edtior, because in a new scene, the materials are not yet loaded?

UPDATE: Just tested same scene in Max 2022 + Corona 9, there is no crash, works totally fine with all the tweaking of osl maps in material editor.

Hey there,

are there any updates on the issue since February?
I experience the same problems the members before me described: Constant crashes since I have some wParallax planes in my scene. It doesn't necessarily happen after the first Interactive Render - the crashes are pretty random, but quite constant in their appearance.

I use Max 2023 with Corona 9, both updated to the latest product versions.

Same for me, even the new version of parallax shaders crashes randomly but inexorably. it is totally unusable in production because it is far too unstable. I tested them on max 2022, 2023 and 2024 with corona 9 without success..

@mienda

Well, I wouldn't go as far as calling it "totally unusable", as I managed to finish a competition, using parallax for the retail areas and thus saving tons of time and render ressources, but it surely is infuriating and far from how it should be.
The workaround I went with was setting up the parralax while the scene was still lightweight. Had to put up with constant saving and occasional crashes for a while, but after the parallax planes were set up, I just made the layer they were on invisible and was able to continue working without further crashes. Then, I'd just turn them on for preview renders and the final production (4K) and had no problems finishing the project.

Hope the issue will get resolved soon, though. Parallax solutions are a big help and it would be great to be able to use reliably.

Any updates on this? Happens mostly with a lot of Parallax maps in the scene.

[mienda]

Same for me, I hope it will be fixed soon because I suffered random crashes when opening, manipulating and rendering with all OSL parallax systems (as well with the new version of Wparallax and versions of Evermotion ( archmodels 267 and 271) I tested these materials on 2 different systems (threadripper 3990X and Intel i9 13900HX) with 3dsmax2024 and corona 9 HF3 without success.. These materials are not reliable at all and are unusable in production.

Thanks

Hi,
I have the same problem, on Corona 10.1 and max 23 and 24 too. I schould render an animation with the maps, but currently this is not possible, since max crashes after the first render almost on each rendernodes...
Anyone found a workaround?
Thanks.

[gabor]

Hi,
has this been solved, or am I missing something? Since the topic has been moved to the solved section...
Thanks.

[Juraj]

Weird, why is this in solved? The OSL wParallax has such a potential to revolutionize workflow in ArchViz but not if it's crash-fest :- (.

It could be the fault of the particular OSL, but not OSL in general by itself since I still use lot of OSL nodes in my shaders that are completely fine.

[aaouviz]

Yep, constant crashes here for me too.
