Houdini crashes instantly

[Francois Lord]

Hi,

We have upgraded to RRv9.1.20 and rez to 3.2.1 over the last few months and we now need to render frames for the first time since April. When we try rendering with Houdini (any method), it crashes instantly. I don't know what else we might have changed. I tried with Houdini 21 and 20.5 which used to work fine. 

What could this be?

The command RR uses is something like this:

\\path\to\rez\rez-env.exe houdini-21.0.440-r1 htoa-6.4.4.0-r1 [...more rez packages] -- "hython" "C:/RR_localdata/renderscripts/kso_houdini.py" -scene "//path/to/scene/scene__simpleKarmaH21.hipnc" -renderer "createUSD" -exportmode true -FrStart 1 -FrEnd 1 -FrStep 1 -FPadding 1 -FName "////path/to/scene/geo/scene__simpleKarmaH21.usd_rop1.usd" -FSingleFile True -rop "/stage/usd_rop1" -threads 20 -renderDemo False -avFrameTime 0 -AASamples 1.0 -noFrameLoop True -unlockAssets True -PyModPath C:\RR_localdata\renderscripts

And the log looks like this, it can't find python311.dll:

R 7| (0) Couldn't load -/bin/python311.dll.

Hi

 

I am not aware of a larger change in RR that would prevent Houdini from starting.

Houdini is used a lot with RR and we did not got any issue reports.

 

Can you start Houdini (via its cached path C:\REZ\houdini\21.0.440-r1\95dd\a\payload\bin\hython.exe) directly and can you start Houdini via Rez without RR?

Yes I can run Houdini via rez and hython from the local path. I even tried as the user the service is running under.

I don't think something changed in RR itself, but probably in the way our IT staff installed it in the machines for this year. 

I have a hard time troubleshooting this because I don't know what RR is doing exactly before running the process. I copy-pasted the command I see in the log and tried it in a terminal. It runs hython correctly but it fails with this message:

C:\REZ\houdini\21.0.440-r1\95dd\a\payload\bin\hython.exe: can't open file 'C:\\RR_localdata\\renderscripts\\kso_houdini.py': [Errno 2] No such file or directory

Hi

 

 

> can't open file 'C:\\RR_localdata\\renderscripts\\kso_houdini.py

Please change the user rights for the folder C:\\RR_localdata.

Add your user or all users for read/write.

Inherited permissions should already be activated, so it should affect all subfolders and files.

After a client got a job, it creates a batch file C:\RR_LocalData\C_...bat

You can execute this batch.

You have to

• Change the job settings: Disable the job option “Local Render out”
• Let the client get the job.
• Uncheck “Enabled” within the rrClient UI to prevent it from getting a new job
• Two ways to start:
  a) Start the C:\RR_LocalData\C_...bat from the explorer.
      You may add the commandline “pause” to the end of the batch file to prevent it from closing.
  b) Open a terminal and execute it.
       But in some special cases you may not be able to run the batch twice as some environments are already set.
       A clean env is recommended.
       You may run this commandline to open a new command prompt:
               start cmd /k C_Elliot10_A.bat
  
  
  

 

 

One important step in finding the difference is comparing the environment.

Before you do the batch file test

edit the file RR\render_apps\_setenv\all\_global__inhouse.rrEnv

and add the line

[Exec] set

This prints all env vars.

Instead of just running the batch, pipe it into a log file:

start cmd /k   “C_Elliot10_A.bat >C:\RR_LocalData\_output.txt”

 

 

Use a file comparison app to compare it with the render logfile in RR. (The one that was used to create the batch file)

Get the job {ID} of the job in rrControl

RRs logfile is located in RR/rrJobData/<Project>/{ID-DirstLetter}/{ID}_..../log/

 

 

 

PS:

Houdini 21 is about to be tested for issues in the next few days

Houdini 20.5 was used a lot.
