Vray5 update2.2 | VFB | Interactive Rendering | CRASHING

[troy@visualiii.com.au]

3ds max 2022
AMD Ryzen Threadripper 3990X 64-Core Processor 2.90 GHz
NVIDIA geforce RTX 3090
128 GB (128 GB usable)

Max scene: Face count 6.6mil
Xref scenes: 2 Loaded

When initiating IR, the scene appears within the VFB correctly. Can manipulate camera and light settings. However when i stop the IR, the max scene crashes all the time. This doesn't always happen. With small scenes it's fine. Only large scenes.
I have a pretty good machine that i'd thought would be able to handle this.

May i ask for Chaos group to shed some light on why this happens?
thank you

Hello,

Do you have any third party instancing plugins in that scene like ForestPro/RailClone ? Do you get crashes if you disable them ?
Another thing - once Max crashes it should write a crash dump in the temp folder - could you send one ?

Best regards,
Yavor

I have the latest forest pack
Dump file.. I think this is it.

For note:
An xref is of the city, so it has a lot of maps....a lot, and geometries. Once i disabled this xref, IR worked as it should. This xref may be the problem, however, i went and opened the problem file again today to see if i can get the latest DMP file for you. Started IR, and closed it, expecting it to crash....but nope, didn't crash....so now i'm really not sure why.
Anyway, see what you get out of this dmp file.
I'll keep doing what i do and if it crashes again on Monday, i'll notify you.

Thank you for your time Yavor

Can you try with a new stable nightly build (https://nightlies.chaos.com/main#/vr...e_5.2/20220224).

Used the latest nighty build.
So far crash has not occurred, however haven't pushed it hard though.
Will update should the crash occur again.
thank you
