VRay Proxy objects and AMD processor problems

[bdahlinger]

Hello,

We have a render server setup with a variety of different computers. Mostly Intel, but about 15 AMD. There's a scene we have with hundreds of instanced proxy objects. On the Intel machines, frames render fine, on the AMD machines the proxy objects only render half of their geometry, as if they were cut in half. It will render either the top or bottom of the proxy object. See images below:

Thanks,

Bill

vray 1.5 rc3

Is this reproducible in a scene with just 1 of those proxies or only when they are in this particular configuration?

Cant say I have ever come across that.. then again I only have 1 AMD machine.

Just for a bit more information. Are you all machines running the same OS? If so which one? XP.. 32/64bit?

[ene.xis]

I run vray across 8 machines being 2 of them AMD and the rest INTEL and i never came across anything like that...

windows xp
max 8
vray RC3

Thanks for all the replies.

Got real busy, but I'm going to dig into the scene soon and find out what's up. All the machines are running 32bit xp sp2. The proxy objects are on a network drive, not local on each machine, naturally. All machines have only 2gb ram, and this scene gets pretty high up on ram usage. All of the AMD machines are all dual - dual cores. The scene is motion blurred, adaptive qmc sampling, Quasi-monte carlo GI. Rendered from max 8.

Thanks!

There is a slight chance that it is a network issue; each computer will keep the proxy file open so that it can load portions of it as needed; if too many computers try to access the same files some of them may fail.

But why just the AMD boxes?

[DaForce]

I can only assume the boes were bought at different times, so maybe the AMD boxes are setup slightly different and thus causing the problems.

He could try copying the proxy files locally to each machine and render that way.. see if it fixes the problem, that would atleast point to a possible cause.

weird problem, we have a mixed farm of amd and intels and have no problems, except for backburner...... but thats a side issue

the proxy objects are located on a file server with win server, so it allows plenty of connections.

Are you using UNC paths or mapped network drives?

UNC paths are more reliable.

UNC paths are more reliable.

hi,

mapped network drives. (edit: changed to unc, problem still on one machine)


i've simplified the scene down to two proxy objects, fixed sampling, no motion blur and still see the problem...but now it's only rendering improperly on ONE of the amd machines. So now it IS rendering on the other AMDs, just not one. The one it's not rendering on is very similiar to the AMDs that are rendering correctly. Argh. I'll keep trying things. Thanks for all the help!

It might be useful to send me the simplified scene over to vlado@chaosgroup.com; if I can reproduce it (I have an AMD machine as well), it will save you a lot of trial and error.

Try turning off any antivirus and firewall software (including the built-in windows stuff)

Hello,

I have the same problem with Vray 1.5RC2, AMD and intel renders (all winxp64)
File server is Windows Server 2003 32Bits.

Sometimes the AMD machine don't load the proxies...

I don't use UNC path...


The only solution I have is to restarts all servers... and after it is ok...

Any idea Vlado ?

Best regards
