Environment Variables - Houdini

[chrisdunham95]

Hello all, 

So ive been customing the Houdini env variables within the Houdini docs folder. All working correctly with my job and hip file paths set as I wish. 

I was wondering is it possible to reference a system environment variable within the Houdini env variables script?

(So set a environment variable called HOME to a certain path in the systems env variables)

(Then call HOME within the Houdini env variables to set JOB or whatever). 

Any guidance or help appreciated as always

Thanks

C.

Generally speaking you should set system and other environment variables not related to Houdini in the shell, or to the system, before launching Houdini. You should not use Houdini.env for production use like that. I do not believe it will let you set non houdini environment variables. Plus there is no reading from the Houdini.env . Though that would be easy to test pretty quickly if something has changed.

Usually having a python like wrapper that injects all the variables into a shell prior to launching is the best. As you can use this same system on other DCC too. 

Also side note, If you are messing with $HOME you should try and use $HOUDINI_USER_PREF_DIR instead. There are some known programs that do try and use $HOME, which is why SESI made the $HOUDINI_USER_PREF_DIR so you don't break other stuff.

Hope that helps
