distributed rendering / Textures not found

[pechart]

Hi,

i think this is a common problem, but i'm a little bit stuck on this by now.
I have a workstation, some renderslaves and a fileserver. Workstation+slaves are on win7prox64, fileserver is ubuntu with some samba-shares. Maya2010x64, vray 1.5 nightly 11509.

I made a very simple testscene, which renders fine in most cases:
- when i render directly out of Maya on the workstation without DR, textures on fileserver
- when i render directly out of Maya on the slave without DR, textures on fileserver
- when i render directly from Maya on the workstation with DR enabled, textures copied to the same local directory on the slave

But i only get black buckets from the slave if i render the scene on the workstation with DR enabled. Firewalls are off, so i have no idea right now.

So, thanks for any helpful ideas!

Do you get any warnings or errors from V-Ray related to the textures?

Best regards,

Nope, only good ones like

Bad network, see that every day.

Hmm, okay. Could you be a little bit more specific?

[olivervfx]

Different operating systems or connection drops, (if u can try windows to windows...that way you can
determine its not the operating system)

Same as back in the old days, Tiff on a Mac or Tiff on a pc, would read differentely.

The precision in Float on Ubuntu and Windows can be different.
It could completely calculate a different number (if i'm not mistaken)..

But Ubuntu is only the fileserver, I really don't know how that could influence the data exchange between the rendermachines (which are all on win7). But on the other hand I really don't know very much about that things .
I'll setup a share on a windows machine where I'll store the project and give that a try.
(And isn't that a pretty usual setup for working environments? Linux fileserver, windows workstations?)

[olivervfx]

Aaaah ok, nope should work.. Sorry, read the server with ubuntu wrong.


Did you go onto your main workstation and added all the servers in the distributed rendering dialog in render setttings..
(try by name or IP)

Then it should spawn... Maybe still a network related writing issue.

O.

Another test,


Put the file on the workstation on (not on the fileserver) so on its local drive.

Render it with Distributed Rendering on, and have your slaves in the list all enabled.
That should work for sure.

I'll try the last one as soon as possible, thanks.

Nope, still no luck when i put the texture on the mastermachine. Only black buckets from the slaves.

EDIT: Ok, i uninstalled the nightly and installed the stable release and now it works. Maybe there was a problem with running the slaves as services? 'Cause now i'm starting the Slave manually.

EDIT2: It also works with the nightlys when i run the slave manually. Is the service maybe using different ports?
