I am getting a crash in 12 when I move around decals with IR running.  Max 2025.  Anyone else seeing this?  I was able to move it around without a crash at first, but then I did a 'shift drag' of the decal to duplicate it and since then that decal has been crashing when moved during IR.  I even tried deleting the duplicate\instanced decal and IR still crashes. 

If you can't easily replicate this I can share a scene.

Thanks,
Dan

Hello there, im getting a weird bug on almost all of my scenes. the render would go smoothly and run normally then all of a sudden I would get a ram implosion where 3ds max will chug through all of my 128gb of ram and the whole system gets to be in a shock kind of state till I turn off 3dsmax, it happened on 4-5 scenes now with no reason to chug the memory at all, no forest pack or anything either.

Could you please contact us here and attach a sample scene where the issue can be reproduced? https://support.chaos.com/hc/en-us/requests/new
We are currently looking into similar user-submitted issues, however we are not able to reproduce it so far - https://forum.corona-renderer.com/index.php?topic=43118.0

the thing is its unpredictable, the scene would work perfectly once I restart max and would work normally, although I realised that turning (conserve memory) option in the performance tab would fix it although a bit slow its a lot more reliable, is there a way to change the limit how much memory to conserve in the system? so I can manually set it to use 100gb instead of 128 and choking the PC

It doesn't work like that. The "Conserve Memory" option is a special switch inside the Embree libraries which Corona uses to speed up rendering. So you gain some RAM at the cost of rendering speed, but it is not something you can customize or set in 3ds Max / Corona at all.

Then could that be where the problem resides? as once turning that option on its stable again.

How much RAM do you have and what is your RAM usage during rendering? Is it possible that you are simply running out of RAM because of scene complexity? That's why I requested a scene. :)

I have 128 GB and the scene is far from complex XD, will be sharing a file to better understand this but my usage usually hovers around 90-95% during the usual rendering session.

In case of 90-95% RAM usage, slowdowns/freezes/crashes could be definitely caused by not enough RAM. Even if it's not 100%, it may not be enough for the system to operate normally.
Here is some further read:

Q5: Why do applications slow down even when the task manager shows memory not being 100% used?
The reported memory usage is actually a small lie. System usually uses the free memory for data caching.

Whenever an application writes data to the hard-disk, the operating system just stores this data in RAM and then proceeds to actually write the data to the disk later so the application can immediately continue without waiting for the write to complete.

Later versions of Windows also try to detect the most used applications and preload them into memory so that they can start much faster.

All this cached data is usually not included in the task manager as used memory, but still must be accounted for when checking the memory usage for performance reasons because if an application requests additional memory, the system must first free it by writing the cached data on the hard-disk.

This is the same for me - my scene was far from complex, i have 192GB and the scene i was working in when it happened was literally a few boxes.  There's absolutely no way i was running out of RAM.  I'd say it was about 50 boxes, no chamfers etc (think blocking out a kitchen).  I've just checked and i've since made the scene more complex and it still only uses less than 10GB when rendering at 6k.  But when this 'leak' happened, my RAM usage shot up over the 192GB to the point my entire PC became unusable

Unfortunately, we are unable to reproduce it so far, even using the user-submitted scenes. Just a reminder: if you ever experience it again, please contact us with the problematic scene and a short note explaining how to trigger the leak.
