Python for Artists

Force the entire scene to cook (all nodes)

for node in hou.node("/").allSubChildren():
    node.cook(force=True)

Print the full path of the current Houdini scene

print(hou.hipFile.path())

Get the version numbers in the filename

hou.hscript('echo -n `opdigits($HIPNAME)`')

What platform is Houdini running on?

hou.applicationPlatformInfo()

List all the environment variables

import os
for e in os.environ:
    print(e, os.environ[e])

Increment number at the end of a text string. This is the algorithm used by Houdini to generate uniquely named child nodes inside a network.

hou.text.incrementNumberedString( hou.getenv('HIPNAME') )

Reload a module, useful if you make some changes to the module.

import importlib
importlib.reload(module)
