Maya Ram limit?

[hansesurfer]

I am using many particles in my scene.
At about 1 mio particles, When maya uses more than 1.5 gig ram, it crashes.

So, I do not know if its a restriction of windows ( I have read a threat about that from 2004), or if maya does not like more than a million particles..

If its a restriction that can be circumvented (I have 4 gig ram) can anyone please tell me how to do this??
I am using maya 6.5 here...

Thanks!!!!!!

the syetem is restricted to about 1.5 gigs per thread. So no one prog could use more than thatkind of slice.

Tough if you like and have the neweest maya you can set a /3gb switch as startup option and then the winodws syetem lets you use more than that, allmost up to 3 gb to be precise and maya can use it (but only maya 6.5 and up.

Hi Jooja,

can you tell me how and where I have to set that flag??

I really have no idea how to do that...

thank you!!!

[joojaa]

boot.ini its in your startup drives root (its a hidden sytem file so be sure to have show hidden syetem files ON)

[hansesurfer]

yeah.

But what do I have to write in there?

..(sorry for that question;-)..

[joojaa]

just add

/3Gb

on one of the startup lines (this is one of the lines after [operating systems] tag) after /fastdetect or whatever switches you happen to have. more on his can be found in the microsoft knowlege base.

I do suggets you make two boot options tough one iwth /3gb and one iwthout as you might not want to run in 3gb mode all the time. Also this may save your as one day.

[hansesurfer]

okay, so thats how it looks. Unfortunately maya still crashes!!
have I done something wrong or is it a maya problem????

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)WINNT="Microsoft Windows 2000 Professional" /fastdetect
/3Gb

[joojaa]

the /3gb is on the same line as??

multi(0)disk(0)rdisk(0)partition(1)WINNT

Because is should be. otherwise it does not mean anything. its sswitch for the startup. more on thi can be found at

tough it is cetrainly possible teht the crash is caused by you graphics card and not maya. NAd you do have maya 6.5 RIGHT! because everything piror to 6.5 is not large address aware.

(also incidenttaly windows needs to be restartted for it to take effect bu you knew that!)

[hansesurfer]

don`t know if I understand you right.

/3gb has its own line, isn`t this correct?

I have a leadtek 6800gt
if its the graphics card, do you think a quadro wouldn`t crash (tought question....

[hansesurfer]

oh sorry, for unknown reason I didn`t read your whole post, so lets test first again;)

[joojaa]

yes se the link!

Well personaly i can easily pump 1 mil particles.

[joojaa]

also incidenttaly maya does not crash fro me it just informs taht theres a memeory exception and stops drawing the particles.

[hansesurfer]

hmmm, so it seems that the problem is that I have about 2000 particle objects. with fewer particle objects maya does not crash, but stops building after 1.5 gig are reached.., as you said.

And this happened althought I added the extension to the boot.ini... (now I choosed windows xp)

so jooja, can you really use about 3 gig for maya???

[hansesurfer]

okay, the problem was that I had about 600 000 faces in the scene.
Particles alone don`t cause the crash. The additional faces do it!!!
