muhamedthufail Posted May 17, 2012 Share Posted May 17, 2012 Hello everyone .... i recently bought a pc 16gb DDR3 AMD Phenom 1TB HDD 2x1GB ATI GPUs .. My problem is that no matter what i do .. None of my VRay scenes use enough RAM [ it seems so ] ... Some suggested to increase the poly count .. i did some tweaking in Vray System tab ... Memory allocation : Static But still its nt using more than 5GB ... What should i do ? ... is there any other settings ? n BTW ... i did disabled my Page File as well as i wanted my RAM to b utilized instead... Nothing seems to work ...

RyderSK Posted May 17, 2012 Share Posted May 17, 2012 I suppose you do have 64bit Windows installed, and 64bit Max with Vray, so then, try using dynamic Vray, and simply increase the amount. Link to comment Share on other sites More sharing options...
muhamedthufail Posted May 17, 2012 Author Share Posted May 17, 2012 Hi Jiraj .. Thanks for the reply .. i've been cheking your blog .. yeah .. i changed it to dynamic n gave 14400MB for it .. but sadly nothing happens .. Even now am rendering a bath concept n its using only 5GB of my RAM n it has 240,000 of polygons Link to comment Share on other sites More sharing options...
Chris MacDonald Posted May 17, 2012 Share Posted May 17, 2012 I wouldn't expect a model of only 240,000 polys to go over 5GB. I don't see the problem? Link to comment Share on other sites More sharing options...
muhamedthufail Posted May 17, 2012 Author Share Posted May 17, 2012 (edited) so what's the count of poly's that i might need ? and also i have 4x4GB DDR3's installed in my PC ... i saw somone talking about a setting in BIOS is that necessary ? Help .. Edited May 17, 2012 by muhamedthufail Link to comment Share on other sites More sharing options...
Chris MacDonald Posted May 17, 2012 Share Posted May 17, 2012 (edited) Several million. If windows is showing your full amount of RAM (Which I presume it is?) then you shouldn't need to change anything in the BIOS at all. Set VRays default geometry in the settings to "Auto" - this will automatically switch between static & dynamic when needed. As for not using all of the ram - that is simply because your scene doesn't push VRay hard enough, it simply doesn't NEED to use all the ram. If you really want to push VRay to the limit then you should probably load in a few dozen seriously large trees from evermotion and instance them a few thousand times.

erickdt Posted May 17, 2012 Share Posted May 17, 2012 Why do you want to use all of your RAM anyway? The amount of RAM it's using is the amount of RAM it needs. It seems silly to push it further than your scene requires... E Link to comment Share on other sites More sharing options...
Scott Schroeder Posted May 17, 2012 Share Posted May 17, 2012 Why do you want to use all of your RAM anyway? The amount of RAM it's using is the amount of RAM it needs. It seems silly to push it further than your scene requires... E Exactly, it's like setting your car engine to be flooded with gas instead of letting the engine control it's own gas consumption based on it's own need. Vray won't use all of your RAM if it doesn't need it. You simply don't have enough stuff in your scene, but don't just add stuff to max out your RAM. That's not very wise either.

salvador Posted May 18, 2012 Share Posted May 18, 2012 I think the itch about it is that we would love for Vray to use as much RAM as possible to finish the job faster. Yet, Muhammed, you need to read more about how Vray handles the different procecess of a render and know that it's all not just RAM in play. From loading maps to calculating GI to computing AA to producing the final image it's a bunch of things going on, from CPU / GPU (if used) / RAM. I wouldn't worry too much about it. I have 8GB and yes, I've been near the limit in some cases (several million polys inside). One wise thing to do is always try to keep your scene as light and free of clutter as possible. There are many ways to renders millons of polys without actually having them as native geometry in the scene. Max can easily crash this way and it wouldn't be Vray related.

muhamedthufail Posted May 18, 2012 Author Share Posted May 18, 2012 :-O .... instance trees like thousand times ? .... Alr8 .... yea u r right .. i have lots of RAM in my pc n i just had this weird feeling that am doing somthing wrong which keeps the VRay from using it .. Wel Thanks for your Reply ... Really appreciate it Link to comment Share on other sites More sharing options...

Nic H Posted May 18, 2012 Share Posted May 18, 2012 adding more trees and cars will help - also render to around 10000 px Link to comment Share on other sites More sharing options...
