Vray Render Is too slow. Unknown reason.

[carlomoufarrej]

Hello everyone.

 

Vray render is too slow for some reason, although it used to take about a max of 20 mins to render. Don't know the reason. Please help me clear things out.

 

Here are my PC specs:

Processor: Intel XEON CPU E5-2620 0 @ 2.00 GHz 2.00 GHz (2processors)

RAM: 24.0 GB

64 bit operating system

Nvidia Quadro 4000

 

Please find attached my Vray render settings screenshots.

 

I'm rendering a scene of 496,311 Polys at a res of 1200/720

 

What I am currently rendering is a whole almost empty Townhouse flat. Rendering time calculation shows 4:59 mins, when i don't think it should take that long, at least it didn't used to, so I presume I must've done something wrong with the settings, but I can't seem to figure it out. All materials subdivisions were set to a max of 8, all are vray mtl.

 

Thanking you in advance.

To answer any of these question is very hard if there is not at least one image of what you are trying to render. Long render time can be generated for many reasons, Size of the image (pixels) quantity of polygons, amount of glossy materials and samples for them, amount of reflections, displacements, proxies and many others. By your screen shot your values seems to be fine for test rendering, but if you have any of the elements mentioned it will increase your render time.

Also first as a rule of thumb always setup your Dynamic memory limit around 80% of your total RAM memory, if not VRay will start to dump in your hard drive the memory overhead that create while rendering. If you don't have a fast SSD this will be very painful.

Hi Francisco,

Thanks for your respons.

I understand the v-ray settings frome the times point of view.

We have hexa-core amd 3GHz processor window xp 64 bit ,16 gb ram 3DS max 2011 and v-ray 2.002 and it took 2 approx 2 hours for a test render

 

for test we try the same file on Intel xeon E5 2620 36 gb ram,windows-7 2GHz processor, 3DS max 2011, v-ray 2.002 and it took more then 24 hours.

 

I tried hot fix service packs etc for v-ray and its not helping me.

 

I thought its may be windows 7 with 3ds max 2011 giving problem.

but now problem is Xeon 2620 bios doesn't support windows xp 64 bit.

 

Please Help

 

Regards,

Harsh

Are you rendering a bird? A plane? Superman?

 

Vray 2.002? If you have all of the fixes you should be up in version 2.40.xx

 

What are your settings? If you are rendering something that takes 24 hours it's probably in your scene and/or render settings and not the windows version you are using.
