Hi
I have just upgraded to 1.5 Final but found that when trying to render to other machines which are slaves - max crashes on the main machine.
When the main machine doesn’t crash, the DR doesn’t draw any help from the slaves.
Very strange situation - has anyone experienced this ?
thanks

Are all the PCs (slaves) updated to the same V-Ray version and set correctly?
Best regards,

There is a bug which is already corrected for the next build, but in the mean time, on the render slaves, set the environment variable VRAY_DR_SUBNET to 0.0.0.0 and it will be fine.

Hi Vlado / Candelero
Thanks for your replies, I have had a good look but where can I find this environment variable ?
thanks
N
You must create it from the Control Panel > System > Advanced > Environment Variables; it will prevent V-Ray from sending a notification message to the client machine when 3ds Max starts (which is what caused the crash on the client).

Thanks Vlado, that seems to have done the trick but, I cannot get the slave to help with the rendering of the image on the main machine.
You will have to start the slave before starting the DR rendering on the main machine, like with previous V-Ray versions, for the time being.

Do you mean having the VRayDummy90.max open and on the taskbar before hitting render on the main machine ?
Yep, exactly.
Best regards,
Vlado
Right, I always did that so, thats fine but, I have another problem which doesn’t make sense.
The machines in this room are as follows:
Main machine - full Max 9 64bit and VRay 1.5 Final 63 bit
Machine 2 - full Max 9 64bit and VRay 1.5 Final 63 bit
Machine 3 - slave for DR & BB - (currently not communicating with the other machines)
When I render from the main machine all the buckets rendered by Number 2 are without the texture maps. There are no missing maps and everything is correctly UNCed in the main model.
When I render the same model on machine 2 distributing the rendering to the main machine - all the buckets render fine.
I had to create the environment variable on machine 2 because it was crashing the main machine but now I think this is preventing the textures from rendering out from machine 2 during DR.
This is a weird mess.
Ok, the environmental variable has been removed from machine 2 but the textures are still missing from its buckets.
The environment variable does not affect the textures in any way.
For the missing maps, you may be able to get more information about the issue if you turn on the “Check for missing maps” option in the System rollout of V-Ray before submitting the scene; this will cause the DR slaves to check if any files are missing before the rendering begins and you will get a warning about this; to check which files are missing, see the vraylog file on the render slave. This might help to shed some light as to what is going on.

Hi Valdo
I’m getting the main machine crashing when the VRaydummy is opened on machine 2.
Both machines are running full versions of max and vray.
I haven’t been able to test the missing textures yet.
Yep, this is why you need the VRAY_DR_SUBNET environment variable; it will stop the crashes.
Best regards,
Vlado
Hi Vlado
This is what I get from the VRaylog.txt.server file on the slave machine 2 when it attempts to render;

Yep, looks correct to me - if there are missing files, the slave will refuse to render the scene;
The reason for the missing files is that V-Ray cannot find them for some reason; are these files located in the correct places? Are you using UNC path names or mapped drives? Might be worth a try to copy the textures locally and see if that works.
Best regards,
Vlado
All the files are located correctly as per UNC paths on the server.
When I open the same model on the Machine 2 - it renders fine also using the machine 1 as a slave !
Machine 3 is still not communicating at all.
All the machines worked perfectly before I installed 1.5 Final 2 days ago so, something has gone very wrong since the install of 1.5 Final - do you know what this might be ?
In that case, you can try to go back to an earlier build and see if this works; as far as I know, 1.5 final is not in any way different in this regard than previous builds.
Best regards,
Vlado
For a clean install do I uninstall everything through Add/Remove Programs then go into Explorer and delete all Max 9, VRay and Wibu files from :C\, Program files and Common Files ?
Yep, that should be it.
Best regards,
Vlado
