Re: Distributed Render

Hi.
I think it's a problem in the exporter paths.

Assuming that your server name are SERVER
And you've shared C:/ folder with the name C.
So the C:/ path in the slave machine will be:

\\SERVER\C

But if you take a look at the vrscene.txt in the slave, you i'll see something like this:

...
#include "\\SERVERC:\render\scene_geometry.vrscene"

But it should be something like this to work:

...
#include "\\SERVER\C\\render\scene_geometry.vrscene"

It's not a good solution but you can hack the exporter to correct the paths:

change this:
sfile.write("#include \"\\\\%s%s\"\n"%(hostname, filenames[f]))

to this:
sfile.write("#include \"\\\\%s\\C\\%s\"\n"%(hostname, filenames[f][2:]))
(Assuming that C is your sharing name of the C:/ in the server.)

Its not a problem - this part is just not finished. Its currently in development.

Re: Distributed Render

Hi,

I'm running OSX and would like to get the distributed rendering working. Is it possible? Or is it still something to look forward to?

Thanks,

Re: Distributed Render

Hello everybody,

Could anyone give me some highlight on setup of DR please? (nevertheless the script is still in progress)..
How does this work?, Do render nodes access one common directory on render manager computer or do they receive full packets with scene, textures etc. to their own shared directories?
Which are which in the "V2B" interface?
Im' unable to set network paths ("//computername/dir") in the script interface, only local "disc:/directory" notation is allowed. (Or am I missing something)
How does the typical setup should look like? (in windows environment).

Tanks in advance!

Re: Distributed Render

@voytov, DR is not finished yet.
Today chaos group fix some bugs in V-Ray Standalone and I think I finish DR next week.

Re: Distributed Render

@maces, only ready for Linux(master)->Linux(nodes). Now I'm tesing Win-Lin configuration. Win-Win will be a little later.

Well, that sounds like a win-win situation! Har har har...

Re: Distributed Render

@Laxy, when saying "Linux" I mean any unix-like OS supported by V-Ray so in includes MacOS support =)

So you say DR is ready for Linux Master and Linux Nodes, does that means something is already working for OSX too?

Re: Distributed Render

@Laxy, I guess so =)
A little howto:
1. Create directory /render/
2. Activate DR and set this directory as exporting directory for DR in exporter.
3. Share this directory.
4. Mount this directory on nodes on top of the directory where vray recievies scene file. Its easy to find where vray recieves scene file by watching log window on the render node - there will be smth like Reading scene file "/tmp/vrscene.txt". So, vray recieve file to /tmp/ so mount this directory as /render/ (same name is vital)
5. Now as usual press "Export meshes" and "Render".
Hope this work =)

You can run vray in render node mode like this: vray -server
