Checking if your instancefile files exist

Checking if your instancefile files actually exist...Cos sometimes...they don't! Stolen from MikeB

Paste this into a Python node:



import os

node = hou.pwd()
geo = node.geometry()

geo.addAttrib(hou.attribType.Point,'exists',0)

for pt in geo.points():
    file = pt.attribValue('instancefile')
   
    if os.path.isfile(file):
        pt.setAttribValue('exists',1)
    else:
        pt.setAttribValue('exists',0)
