RAM problem, it crashes

[sMs]

hi

 

looking for ur help =D

 

i have 2.75G RAM on my pc

my video card is Geforce 6600 GT OC 128RAM

pentium 4 3.19 GHz

and sometimes when i do some renders... i get a vray error saying... not enough memory...

 

so my question is... wtf is wrong?? lol maybe i need a better video card like 256/512RAM instead of 128 RAM?? will this help??

 

can u tell me whats wrong? is it my my pc?... i think i got a good pc for rendering...

 

PS: 3ds max never uses all my 2.15 G ram... the most he goes is around 1.5G RAM

I know your frustration. And so do half the Vray users out there. With the new features that came with 1.5 it must require a lot more memory then previous releases, because I never had the problem before. But now, my proccess goes like this: 1- I render it just as usual in the max frame buffer. If it ends up crashing due to memory, I change to the Vray frame buffer. If it still crashes, I then resort to rendering a vrimg. There are some good threads explaining how to do that on the chaos forums. The problem I have with rendering vrimg images, is that in some interiors, I make adjustments in the curve editor from the Vray frame buffer, but the vrimg does not keep that information. What then, you'll probably say get yur lighting right in the first place s o you won't have to adjust the curve editor.

 

Anyway, I don't know if that helped at all. It has also helped me as I keep my texture images under 1800 px.

for stills I get round this by rendering in fairly ad-hoc passes. Displacement is the real killer. Keeping bitmap sizes down is good advice in the previous post. Someone posted a thread full of advice about this issue about a week ago. They recommended rendering through backburner and closing max (amongst other things) as max itself uses a hefty slice of ram.

 

Animations are a different animal. What are you working on? A render may provide some clues...

try increasing the dynamic memory limit in the System rollout for Vray. This has allowed my renderings to complete a few times in the past when i would get memory errors. If it's anything like previous releases with v-ray I'm assuming that this is something you only want to do when you really need to, cause it will slow down your render a bit as the engine loads and unloads info into the memory. This is also a good fix if you see that you are "unloading geometry" a lot when rendering a scene with displacement.

 

someone else may be able to explain the pro's and con's of this better than I can, but I do know it has allowed me to render scenes before that would crash out on me, but like I said normally you will have a time trade off.... but as opposed to crashing and not having anything rendered, it's a fix.
