houdini/redshift render fails on RR

[Adrian Wyer]

up-versioned houdini/RS and as always broke everything!

error from startup on each node seems to be this;

 'findstr' is not recognized as an internal or external command, operable program or batch file.

then the node quits...

houdini.env issue somewhere? i've copied the local .env stuff into 

S:\RR\render_apps\_setenv\all\houdini__inhouse.rrEnv

am i missing something obvious?

Hi

 

By default, RR does not use the houdini.env.
All env vars are set in the setenv .rrEnv files in Royal Render.

 

“findstr” looks like an issue with the syntax in one of the rrEnv files.

 

I need to take a look at complete log and your rrEnv files:
Please select the job in rrControl.

Then execute "Export debug info - selected job(s)" via the menu "Debug".

Please upload via www.RoyalRender.de/upload_r.php

 

 

 

Otherwise, If it would not be “findstr”, I would have assumed that Redshift is setup as network installation in RR, but was not copied into RR yet:

thanks Holger... uploaded the debug....

any indication from the logs what the issue might be?

checked the inhouse houdini env file we were using with the previous version of houdini/rs and there's not really anything different

of note;

if we do the rs file generation locally, then just put the render job on the farm, we get module errors, but the frames do render... excerpt of log;

Hi

The Windows env var PATH is broken.

Therefore it does not find any executable, including findstr.

 

The issue are the lines you have added to houdini__inhouse.rrEnv.

$PATH is the Linux way to write end vars.

The houdini.env uses the Linux format, but RRs rrEnv files do not.

 

 

Then you do not need to specify all env vars for Redshift, RR does that for you.

RR just needs to know where Redshift is located.

 

Steps to fix:

1. Redshift
   Please remove  these 4 lines
   HOUDINI_DSO_ERROR = 2
   PATH = "C:/ProgramData/Redshift/bin;$PATH"
   HOUDINI_PATH = "C:/ProgramData/Redshift/Plugins/Houdini/20.5.613;&"
   PXR_PLUGINPATH_NAME = "C:/ProgramData/Redshift/Plugins/Solaris/20.5.613;&"
   
   Then remove the comment # from line
   #RR_REDSHIFT_BASE = C:\ProgramData\Redshift
   
   This is all that you need to do to load Redshift.
   
   
2. OTLScan path
   Please replace
   HOUDINI_OTLSCAN_PATH = $HOUDINI_PATH;$MYHDA;$GR14HDA;& 
   with
   HOUDINI_OTLSCAN_PATH = <HOUDINI_PATH>;<MYHDA>;<GR14HDA> 
   This is the rrEnv format.
   And the & must not be added as RR adds it.
   And it must not exist twice in an env var for Houdini.
