I can't find how the hom finds the global variables, i have some custom ones made for my scene I would like to access from Python scripts.

Word.

You can access them a couple ways.

set MYVAR=5

You can use HOM methods to evaluate the variable values:
>>> hou.hscriptExpression(“$MYVAR”)
'5'
>>> hou.expandString(“MYVAR”)

Also, if you define the variables using something like your bashrc file you can use the os module environment stuff.

>>> os.environ
'5'

dude you rule.

Thanks alot. This is exactly what I was looking for.

is there a hom interface to aliases and variables where you can get and set or do you still need to do this kind of thing?

hou.hscript(“set -g %s = %s”%(var,val))

prob also good to mention here that one will throw and expection if the variable isnt set while the other will just return the empty string (hom)

>>> hou.expandString(“$BLAH35”)
''
>>> hou.hscriptExpression(“$BLAH35”)

Nope, still nothing.
