Is there triangle limit for saving a file?

[terraformers]

i have a scene with 100 000 000 none instanced triangles when i save it, i get the message : "could not save file", is there a limit for triangle count in order to save a maya file?

win7 54 bit
hexacore 3.33 ghz
12 gb ram.
nvidia gtx 480
maya 2010

If there is then i havent seen it. But there might be a reason for it not working out tough, see yoru filesystem has a upper limit to file size wich may become relevant at some point. Its time to reformat the dirve to use bigger file blocks

So lets say your saving amaya ascii file and all your vectors have 8 digits. thats 10+10 bytes per triangle if its the densest possible mesh. thats 2 Giga plus the rest... odds are youd get somewhere around 3-6 times that meaningwe are talking 6-12 Giga sized files. Should be ok but depending on how the sytem is formatted might be too much. Ive seen it happen, and its ajust a stupid choice of disk format thats all.*

*in fact if most of theese are leaves then its probably 10 TImes as much data.

my drive is new and it has a capacity of 1.5 TB.
i only have 10% used.

[joojaa]

yes but what filesystem is it formatted to?

[terraformers]

where can i verify that in windows7?

[thnkr]

RMB click on the drive in Windows Explorer and select "Properties"

[terraformers]

if it s file system then its NTFS.
(not sure if thats the format type)

hmm then there should be no limit however there might be some memory limitation on the computer. Did you try saving in maya binary?

[terraformers]

how can there be a memory limit if i am runing a win 64bit system ?
if thats the case where can i check this and change it?

You dont have unlinitted (and continious) memory now do you?  Testing this right now.

In any case chek your file eprsmissions first.

[joojaa]

ok, it blew up my memory settings and bailed out just before my max swap settings was reacherd.

Seems like my first approach was a bit bad, i now made a scene with 53 2 Mil poly planes with no history. Works fine. Creates a maya ascii file that's a whopping 8.12 gigabytes ascii file. However maya does seem to want to cram a sizable protion of that in memory at one time as maya reserved 1-3 giga in memory for saving the file in chunks. It also seems to use the data 2 times over.

Please note i have skipped maya 2010 because it didnt offer anything new so i did it on a maya 2011. Works and seems like the 2009 is working out too.

OK so the problem is probably how maya caches this stuff. Not much you can do about that. So it may come down to your disk controller. Since i have a raid slapped here mine is pretty good at sustained writes. Writing it out took a loong while but actually maya did something in memory before dumping the file out.

OR it actually needs to have the shapes in separate objects as maybe itts writing one object at a time.
