trying to make pre-render directories

[kleer001]

EDIT: All I had to do was change the channel scripting language to python. That handy little pull down on the right hand side IS NOT for the channel contents, it's for the imported script. Ugh. Totally fixed.

 

Btw, here's some code fixing sideFx's blind side on creation of folders for image planes.

 

----------

 

Sadly the new coolness of "Create Intermediate Directories" doesn't work for image plane folders with global variables in their name.

 

I've already submitted and RFE. And I'm working on some tiny little python to help out, but it doesn't seem to do the job.

 

I've got 5 image planes standard in this pipe I wanna toss together:

import os
import hou

self_mantra = "/out/"+hou.expandString("$OS")
for i in range(1,6):
    chan_name = self_mantra + "/vm_filename_plane" + str(i)
    plane_chan = hou.parm(chan_name)
    plane_chanVal = plane_chan.eval()
    plane_bits = plane_chanVal.split('/')
    folder_name = '/'.join(plane_bits[:-1])
    if not os.path.exists(folder_name):
        os.makedirs(folder_name)

        
Right? That looks fine to me. All the pieces work. I've slapped it into the pre-render script channel as an expression. So, it should run once before the frame starts, right? But it doesn't seem to run at all.

 

Ugh, what did I miss?! Does this work for you? What do you do to make those directories automagically?

and some more code for the remedial home pipeline builder:

import os
import hou

# requires $SHOW/EPISODE/SEQ/SHOT/VER pipeline global variables
# along with the formatted Different File paths like:
# $JOB/renders/${SHOW}_${EPISODE}_${SEQUENCE}_$SHOT/$ELEM/$VER/
# Spec/${SHOW}_${EPISODE}_${SEQUENCE}_${SHOT}_${ELEM}_${OS}$VER.S.$F4.tif

self_mantra = "/out/"+hou.expandString("$OS")
# hard coded to 16 just because 16 layers is a lot
for i in range(1,16):
    chan_name = self_mantra + "/vm_filename_plane" + str(i)
    switch_chan = self_mantra + "/vm_disable_plane" + str(i)
    plane_chan = hou.parm(chan_name)
    if plane_chan != None:
        if not hou.parm(switch_chan).eval():
            plane_chanVal = plane_chan.eval()
            plane_bits = plane_chanVal.split('/')
            folder_name = '/'.join(plane_bits[:-1])
            if not os.path.exists(folder_name):
                os.makedirs(folder_name)
