Corona 12 Major Memory Leak

(1/6) > >>

dj_buckley:
I seem to be experiencing a pretty serious memory leak with Corona 12.

I'm trying to pinpoint it exactly at the minute, but it seems to be when I try to use IR for the first time after merging a 3rd party model into my scene.

The process goes something like this

- merge model
- continue working (no problems yet)
- start IR
- memory leak

but

If I save the scene after merging, close max, reopen the scene and start IR then its fine.

But the memory leak is literally causing my computer to lock out and ultimately crash requiring a full restart.

muoto:
had some issues as well, starting IR and getting white VFB screen, CPU 100%, memory getting high. but no rendering visible
google complained about memory lacking (first time i had this, 64GB system btw)
had to kill 3dsmax.exe

dj_buckley:
I'm on 192GB RAM and it just completely locks out my machine, i'm working in a scene that just contains a few boxes really (screenshot attached) and the file is 45MB.  But as soon as I press IR after merging a new model in, memory usage in task manager shoots above 150GB and then just keeps climbing.

If I catch it quick enough i can end task in task manager, if not then it's a full PC restart

maru:
Does it happen after merging literally ANY model, or only some specific model(s)?
If it's specific models only, could you please send at least one of them which triggers the issue at https://support.chaos.com/hc/en-us/requests/new
Thanks in advance!

dj_buckley:
It's happened with two different models so far, one from 3D Sky, the other from Dimensiva.

I've just tried again with one of the models and it didn't happen, so it's not consistent either.

I seem to have a knack for finding inconsistent seemingly random and impossible to pinpoint bugs :)

Edit:  Might be something, but previously when it's been happening, I've had multiple instances of Max open.  When I tried again just now I only have 1 instance of Max open
