max2020.3 + vray 4.3.01 +Itoo crash

[vypravci hubicka]

Hello,
currently we are converting our studio to max2020.3 + vray 4.3.01 from max 2019. I am experiencing crashes ( on 2 of the running projects already) - it is always in the middle of render, regardless if on the workstation, on the farm via DR, on the farm nonDR, stripes etc. We were absolutely unable to trace anything that causes it, since it crashes immediately during the render ( no beginning phase, no denoising phase, no saving phase etc.) . Also the second project run ok yesterday and after couple production renders overnight I changed only sun/camera position for one of the frames and it suddenly started to crash as well. All projects are originally based in max2019/vray 4.2 and have always run bulletproof. Generally, max 2019 + vray 4.2 was stable combo.
Please let me know on this, also where can I send the vraylog to or anything - I am newbie here

many thanks

Hello,

Do you have camera motion blur enabled ?
Additionally - when a crash happens Max should write a crash dump file called 3dsmax_minidump.dmp in your temp folder (type %temp% in windows explorer address bar). Could you attach it here or send it to our support. The same for the vraylog file.

Best regards,
Yavor

Hello Yavor,
thanks for reply,
I have sent the minidump and vraylog files to support as you suggested. Regarding the camera motion blur, it was checked in the camera rollout in the rendersetup, and unchecked in the Vraycamera properties..... however there was no intention to render any motion blur in this project, these are plain still archviz images.

thanks

Hello again,
it seems like the HDRI used in the environment slot is causing this. Worth mentioning we use quite complicated composite of more HDRI´s which allows us to key/animate specific HDRI for each frame or even mix them. I realize this may sound a little odd, however this is very practical, and in max2019 + vray 4.2. combo we have rendered tons of images this way.
VraySun + this HDRI composite mix in environment slot= crash
VraySun + only one HDRI ( in VRAYHDRI loader obviously) = stable
VraySun + VRsky = stable
VRaySun + HDRI composite but in DOMELIGHT instead of simply put in the envi slot = stable

Can it be something changed in latest version in regard to GI calculation from the HDRI in the environment slot?
Final solution would probably be to use the domelight ( which I belive was recommended anyway?) but I would like to know

thanks

Hello Svetlozar,
I am checking this right now, there was certainly no intention to use unpaid software, especially not from Chaos since we were very satisfied and proudly paid for every head and renderslave in my studio in last 10+ years.

thanks

Thanks for the additional information as well as for the new minidump and vray log files.
We are looking at them now, we'll get back to you shortly.

[Svetlozar Draganov]

It looks like we will need the scene in order to continue the troubleshooting - we haven't found any suspicious things in the log file as well as in the dump one.
If possible, please pack to the full scene including assets and etc and sent it over in the respective case.

Looking forward to hearing from you.

[vypravci hubicka]

......scene sent, thanks

[vypravci hubicka]

Hello Svetlozar,
please let me know if scene received, and if you have come to any conclusions yet

many thanks

Thanks for the files.
We managed to reproduce the issue, it is already added into our bug-tracking system under #VMAX-9502.

We'll get back to you once we have a fix for it.
