instance ass files (not paths)

use instancefile to access geo saved somewhere...

in a point wrangle - 

  s@instancefile=chs("path");

now with the geo node, you gotta add the instance tab and turn on fast instancing.

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)
