Unfortunately I have some serious issues with Corona recently. I’ve been going between 1.2.1 and the newest daily builds trying to fix this, but nothing helps.
Recently almost every scene that I’m working with has trouble rendering or even saving with Corona. ‘Parsing the scene’ and saving files takes ages. I have to wait for parsing to finish for 5-10 minutes on a simple interior scene. When trying to distribute to other machines I have to wait even longer, cause the scene has to save, then parsing… takes hours, not kidding, one scene took 7 hours to start to render. I am working inside a company network, all my files are kept inside that network so it’s all UNC paths. Anyone else experienced this issue? Is there some kind of a simple fix?
In all versions of 3dmax exist problem with file size/
Sometime while saving of file a size file may be bigger and bigger/
especially it happens during the merge operation some models from different libraries and resourses/
it’s problem connected with motion mixer information in scene/
Exist many scripts for clean scene from this problem/
You have to check you file size!!!
ok, 3dsmax was stuck inside hair object creating geometry when the minidump was created. It further seems that the slowness is due to some “fault tolerant” mechanism being used. Accoding to microsoft documentation, when a process was crashing a lot in the past, it will automatically switch it to a fault-tolerant environment (which I guess could be also mega-slow) - Fault Tolerant Heap - Win32 apps | Microsoft Learn
So:
can you try if the problem persists also when using not using hair objects?
can you view the fault tolerant event log (see link above) - is 3dsmax there?
can you try disabling the fault-tolerant environment, or resetting list of applications using the fault tolerant environment? (link above)
go through the rest of my checklist - it is possible that MS windows decided hair & fur is too bugged to run full-speed so it is being run in slower “fault-tolerant” runtime
Yes, it also was thrown into FTH. I’m trying to turn it off completely, cause it’s the only app that’s actually using this, so fingers crossed it works. Thanks!
Turning FTH off in the registry does solve the problem. What makes me worried is that I never had this issue with… well, other rendering engines. This just showed up with Corona. Is there a bottom line to this issue?
Either way thank you very much for solving this so quickly Ondra! Literally saving my butt over here.
I’m calling “not it” on the issue! It was automagically turned on by windows because 3dsmax crashed a lot (which was not necessarily caused by corona - it could be any renderer, max itself, or any other plugin)
Sorry to ‘reopen’ this topic again, but the issue came back for a different scene and this time I made sure that 3ds is not in the FTH list. Maybe someone could have a look and help me out? The minidump file is
I Have this same issue ocassionally with 1.21 and parsing the scene and building acc took forever that i had to hit cancel after an hour. worst thing is windows freezes up then i have to power off the pc cos i cant do nothing else. then one faithful evening( 2 days ago precisely)… i came home and i knew if i dint solve this problem i would be screwed for not meeting the deadline i was given. I simply Opened the Corona converter script that came with 1.2 and Hit the convert all Bitmaps to Corona bitmap and TADA!!! for some reason it worked. the parsing the scene and building acc stage took barely 2mins at close up shots and less than 30 seconds on aerial shots. the scene file size was about 800mb at the time but now i have converted most objects in the scene to proxies. i dont know if u have been working with corona bitmaps the enttire project but i didnt and so i guess this worked for me but you can still give that button a try cos i have also tried the FTH method and dint find 3dsmax there or maybe i dont know how to go about it yet… goodluck
