set $JOB relate to $HIP?

[poppy]

Hi,

Is there a way to set $JOB accorsding to $HIP?

Say, I have

Project

/scene

/render

/cache

My $HIP is /Project/scene

Can I set $JOB to $HIP/../ ? I use both Win and Linux, I have to set $JOB by hand everytime I open in diffrent OS.

Thanks!

Hi,

yes, there are lots of ways

i'm doing it with qLib's "environment_ql.otl" and some env.py

its part of scripts that i use to initialize environment variables, but for certain task it should suffice

site_environment.py.txt

P.S. its not allowed to attach *.py files? :?

Thanks Owl,

However, honestly, I dont know what to do with your kindly provided file. I mean I know way around otl, but never touch python file in Houdini.

Could you please explain more?

[Owl]

First things first

do you know what qLib is?

http://qlab.github.io/qLib/

there is an environment otl that when put in scene initializes python scripts and does stuff for you

[poppy]

Im afraid no. Will look into it. Thanks!

I've set up qLib and most of the otls work with the exception of the environment

 

In Windows houdini.env I set HSITE to point toward the site_evironment.py

 

but I keep getting error on the loading of the file:

 

OOPS: couldn't find C:/Users/myname/houdini13.0/site_environment.py

 

Thanks for any help on this.

Hi,

I'm digging back this old thread because i have mainly this same problem.

 

- I'm in the need for a project oriented structure like $JOB (essentially allowing to sort hip files by shots etc)

- I'm rendering with a mixed operating systems (win and osx), so the path needs to be set via an env variable, $HIP works great for this

- I've tried the new $HOUDINI_PATHMAP but this doesn't change $JOB

 

unfortunatly $JOB is written in the hip file so any attempts to set $JOB in houdini.env fail

 

I've qlib up and running for a long time but this doesn't change anything because getting my hand on python scripts like the one here (site_environment.py.txt) is way out of my head

 

Does a simple solution exist, telling houdini to doesn't include $JOB path in hip ?

 

Thanks

hi, Noel,

assuming your project set-up looks somewhat similar to:

Proj($JOB)/

    Renders/

    Scenes/

        shot/

    Cache/

 

rename  proj_env.py.txt to proj_env.py

proj_env.py.txt

 

place this file into  your project folder,

save hip into scenes folder

add environment_ql node to your scene file

 

try moving whole project to a different location, open hip without redefining project(JOB) manually, does the JOB variable update? you should see it in environment_ql node.

Olala that's working !!!

 

So if i may... 

 

To be perfectly free i would like to move back from the hip file to the actual project folder name without passing through a scene folder, that would be ideal...

 

I assume in the "for i" statement i would write my project name in place of "scenes"

But how can i tell in python to use that actual projectname found to be the actual $JOB seems? Seems if i just remove the "path.pop()", i'm really close ;-)

 

But i have to thank you, actually i understand now how that's working at least

[NNois]

ok got it workin

THANKS YOU !

Hi,

I'm setting up now project based otls and taking your first example file i see:

 

Here you import hda's it's ok and working

OTL_PATTERN = JOB + '/Assets/Otls/*.otl'

But here:

What this part is doing exactly ??

os.environ['HOUDINI_OTLSCAN_PATH'] = JOB + '/Assets/Otls' + ";" + os.environ['HOUDINI_OTLSCAN_PATH']
hda_rescanOTL.rescanOTL()

I'm asking because I don't have a fixed path like in the example but i'm with a path with wilcards and this is not working ...

In my case I have 

OTL_PATTERN = JOB + '/*/hda/*.hda'

how can i add that to the scanpath ?

 

Thanks !

Hi,

if i recall correctly OTL_PATTERN didn't work for me so i manually added all the folders and sub folders with hda's and the forced the refresh. You can walk through the dir tree with:

    def indexPath(directory, ignore_list = []):
        '''index returns list of dirs and subdirs ignoring dirs provided in ignore_list
            like os.listdir, but traverses directory trees'''
        stack = [directory]
        dir_list = []
        while stack:
            directory = stack.pop()
            for obj in os.listdir(directory):
                fullname = os.path.join(directory, obj)
                if os.path.isdir(fullname) and obj not in ignore_list:
                    dir_list.append(fullname)
                if os.path.isdir(fullname) and not os.path.islink(fullname) and obj not in ignore_list:
                    stack.append(fullname)
        return dir_list
