What error message or stop message are you getting. Or is maya crashing. What version of maya. And was the scene created without importing?

When i run the rendering in command line i have no error message but the rendering never finish, and when i try to run rendering under maya as you can imagine i have the free memory is low error message
i use maya 4.0.2

I have the same issue, but I think it is because of ram, I have 1 gig, and I am running at 1.7 million faces, sometimes it just stops rendering when it is constructing shadows as well. It just sits there at 0% cpu usage.

Renderman will solve your woes. Grab Liquid Maya and a free renderer like 3Delight. The other thing is to ask yourself if you really need 1.5 million triangles. Can you break the scene up into layers to render seperately?
You say the render never finished when you do it from the command line, how many lights do you have in the scene? If it's more than 1 it's going to take forever and a day to render. Seriously, split it up into layers, render each each and then composite them together afterwards.

Do you have any shadow maps that are above 2k resolution? Do you have alot of textures? Are any of them above 4-6k rez?

Try turning your texture files into BOTs(lookup makebot.mel in the manuals) or make sure your using .sgi or .iff for textures. This will bring down memory usage by half if you have alot of textures. Shadow maps above 2k rez won't render on windows because they are a huge memory hog(have to use linux to render or raytrace). If any shadows are static then you can pregenerate them. This will also bring down memory usage by alot.

hehe, interresting beaker

Well actually i render my scene in 2 times so it's ok but it's always interresing to find a maximum of way to optimize your render without reduce final quality.

Thanks.

I've heard that Maya can't adress more than 2 GB of RAM. more than that and it can't render so you would have to break it up in to smaller pieces.

Not any 32 bit app in windows can address more than 2 GB of ram(1.5-1.6 gb in reality, 2 gb is just on paper). This is not a maya limitation, but a 32 bit operating system limitation of windows(or any other 32 bit OS).

wow that sucks. When I render the scene that I am working on, I am usually using 1.9 GB of ram. Sometimes it stops and says it's out of virtual Memory. Does that mean 2 gb of memory total? What about your Swap file? I apologise, I don't quite understand how it handles memory. I have heard that MR can manage high poly's better, but with this many faces, wouldn't it talk quite a while to render? Thanks for your help,

Try using the tilewidth flag for render.exe and makes the tiles smaller . This should allow the renderer to work within the memory limitations of windows.

Yes, this means between physical and virtual memory, 1 single app/process cannot use more than 2 gig of ram. Someone on highend mentioned that there are hacks for win2k server and linux so you can use more, but it doesn't always work. This is the big reason why 64 bit processors will be nice to have in the near future for our world.
