DR request received from client xxx.xxx.xxx. using V-Ray version (0). Render server V-Ray version (42001).

I am having trouble rendering via DR using Houdini 17.5.293 and vray standalone.
For houdini I use the vray build: vray_adv_41203_houdini17.5.293_a675c3e5059
And the newest standalone version from the chaos group homepage.

I start vray standlone on the renderserver with the -server command. Then I fire off a houdini render on my workstation. The renderserver instantly gets the request but spits out this error message:
error: DR request received from client >insert ip address here< using V-Ray version (0). Render server V-Ray version (42001).

Honestly I am not sure what I am doing wrong in this case.
Hopefully someone can help.

Well, the Stanalone you are using with DR has probably much newer Core then the one VFH is based on. Since some time we require exact version match.
You could try using vray executable shipped with the archive (but you'll need some tricks to provide Qt libraries, which Houdini has and we are utilizing those ones).

Good to know. I used this thread as a baseline to install vray standlone: https://forums.chaosgroup.com/forum/...work-rendering
What would be the simplest method to get our small render farm up to speed to make use of it with houdini?

You could try using Qt files from your Houdini installation.
Check the screenshot and copy files to the "qt" subdirectory of your unpacked archive (or anywhere else).
Then you'll need to modify "vray.bat" to add paths to that Qt.

[USER="216393"]echo[/USER] off

setlocal

:: This script location.
set LAUNCHER_LOCATION=%~dp0

:: This is where you copy the Qt files.
set QT_ROOT=%LAUNCHER_LOCATION%/qt

:: Add path to Qt 5 libraries.
set PATH=%QT_ROOT%
set QT_QPA_PLATFORM_PLUGIN_PATH=%QT_ROOT%/Qt_plugins/platforms

"%LAUNCHER_LOCATION%/appsdk/bin/vray.exe" %*

endlocal

Then just launch this bat file like: "vray.bat -server"
We need to check if we could ship Qt libraries ourselves, so this should not be an issue in future.

I must be blind because there is no qt subfolder in my unpacked vfh archive.
I also don't seem to find any of the .dll files listed in my houdini installation folder.

ralphr, yes, there is no such, you have to create one and copy file from Houdini installation into that directory (or anywhere else, just then adjust variables accordingly).

Update: I manage to find the needed files in the houdini directory when manually looking for them. For some reason windows search didn't work.
Then I changed the vray.bat and put it on one of the render machines. DR instantly worked.

Thank you for help bdancer
