More people experiencing Max crashes after updating to 6.1? I’ve had multiple files file crashing on opening and some while working in them after I’ve updated to 6.1?
I’m going to revert back to 6 hotfix 3 (if that is possible) and see if it helps.
Hello,
If you still haven’t reverted - can you send us a crash dump from Max when a crash happens. It should be named 3dsmax_minidump.dmp and be located in your temp folder (type %TEMP% in the windows explorer address bar).
Best regards,
Yavor
I have had this and have sent a scene to support also.
I have allready reverted, but the dumpfile is still there (and it’s from before going back to 6 hotfix 3). Where can I send the file to?
You can upload it here or send to support.
Happened to me also. max 2023 crashes when loading one of my large files. Reverted to hotfix 3 and the file loads just fine.
Minidump uploaded here:

I’ve been working with 6 hotfix 3 again all afternoon, zero crashes!
Thanks for the minidump. If you are wiling to do some experiments - can you try to set an environment variable VRAY_DEFERRED_LOADER_NUM_THREADS with a value 0 and then start Max and open the large file in question ?
Other than that - can you share some details on your machine specs - I’m interested in the number of cores/threads ?
I will try tonight. Where do I set this variable?
Here are my machine/system specs:
3ds Max 2023
Windows 11 (version 22H2, build 22621.1265)
AMD Ryzen Threadripper PRO 5975WX 32-Cores 3.60 GHz
Here’s a small guide on setting env vars from our docs: V-Ray Standalone
Thanks for testing this and sorry for the inconvenience.
I’ve set the environment variable as you said, and so far so good!
I’m running a Threadripper 1950X (16 cores, 32 threads), Windows 10. I can try the environment a bit later
why set it to “0”, sir?
0 turns OFF the new feature to defer the bitmap loading as it is the one causing issues.
We’ll try to get a fix soon and you won’t need to set any environment variables.
Hi I encountered also crashing on some scenes open after update to 6.1 (Max 2022.3). Vray log says nothing. Max log something.

Using env var doesnt help 
Also I have crashes after using some new Qt widgets (for example switching secondary gi) and Max log shows some problems with Qt
One note: it crashing after scene in saved with vray 6.1 loaded. If its scene saved before update it loads fine.
Could you try with today’s stable nightly build (Chaos) - it should have a fix for issues with the secondary GI controls. (forum topic on the GI controls - Clicking "Enable GI" in 6.1 crashes 3dsmax - V-Ray for 3ds Max :: Issues - Chaos Forum)
Unfortunately it didnt help with crashing on load
Could you get me a crash dump and/or the crashing scene ?
It should be in the chat. I hope you can see it.
Answered in the chat - seems to be something different from the bitmap issue but still exploring.
