Batch Nuke

My collection of batch scripts for Nuke.

Generate SM

With the generate_smart_vector function you can batch load a video folder and generate the appropriate Smart Vectors for each of them.

# I use the interactive version but you can easily parse cli arguments and use execture (-x) instead
nuke -t
import generate_smart_vector from batch
generate_smart_vector("path/to/my/videos")

import nuke
import os

here = os.path.realpath(os.path.dirname(__file__))


def generate_smart_vectors(folder_path, suffix=".mov",detail=0.3):
  
  path = folder_path
  sm = os.path.join(path,"SmartVectors")
  
  # Onl
  files = [x for x in os.listdir(path) if x.endswith(suffix)]

  nuke.scriptOpen(os.path.join(here,"./sm_template.nk"))

  readnode = nuke.toNode("Read")
  writenode = nuke.toNode("Write")
  # Sets the detail value
  nuke.toNode("SmartVector")["vectorDetailReg"].setValue(detail)


  for file in files:
    # replace the read (using fromUserText to call the callbacks)
    readnode["file"].fromUserText(os.path.join(path,file))
    # get the range
    end = int(readnode['last'].getValue())
    current_name = os.path.split(file)[1].split(".")[0]
    current_folder = os.path.join(sm,current_name)
    
    # set the output path
    writenode["file"].setValue(os.path.join(current_folder,current_name + "####.exr"))
    # render
    nuke.execute(writenode,1,end)
    # save as
    nuke.scriptSave(os.path.join(current_folder,current_name + ".nk"))
