Here’s a python script that translates Lighting Coefficients from the paper by Ravi Ramamoorthi to a expression node. Connect a normal pass to the expression node.

import nuke
import string

def LCoeff2Nuke():
	p = nuke.Panel("Paste Lighting Coefficients")
	p.addMultilineTextInput("Coefficients:", '')
	p.addButton("Cancel")
	p.addButton("OK")
	p.show()

	coeffVal= p.value("Coefficients:")

	#CONSTANTS
	c1 = '0.429043'
	c2 = '0.511664'
	c3 = '0.743125'
	c4 = '0.886227'
	c5 = '0.247708'

	Coefficients =[]

	i=0
	for line in coeffVal.split('\n'):
		if line.startswith('L_'):
			Coefficients.append(line.split()[1:4])
			print line
			i+=1

	expTemplate = 'c1*L22*(pow2(r)-pow2(g)) + (c3*L20*pow2(b)) + c4*L00-(c5*-L20) + 2*c1*((L2m2*r*g)+(L21*r*b)+(L2m1*g*b)) + 2*c2*((L11*r)+(L1m1*g) + (L10*b))'

	expressions = ['','','']
	for i in range(3):
		expressions[i] = expTemplate
		expressions[i] = expressions[i].replace('c1', c1) 	#
		expressions[i] = expressions[i].replace('c2', c2) 	#
		expressions[i] = expressions[i].replace('c3', c3) 	#
		expressions[i] = expressions[i].replace('c4', c4) 	#
		expressions[i] = expressions[i].replace('c5', c5) 	#
		expressions[i] = expressions[i].replace('L00', Coefficients[0][i]) #
		expressions[i] = expressions[i].replace('L1m1', Coefficients[1][i]) #
		expressions[i] = expressions[i].replace('L10', Coefficients[2][i]) #
		expressions[i] = expressions[i].replace('L11', Coefficients[3][i]) #
		expressions[i] = expressions[i].replace('L2m2', Coefficients[4][i])#
		expressions[i] = expressions[i].replace('L2m1', Coefficients[5][i])#
		expressions[i] = expressions[i].replace('L20', Coefficients[6][i]) #
		expressions[i] = expressions[i].replace('L21', Coefficients[7][i]) #
		expressions[i] = expressions[i].replace('L22', Coefficients[8][i]) #

	expNode = nuke.nodes.Expression(expr0=expressions[0],expr1=expressions[1],expr2=expressions[2])

Here’s a python script to submit scripts from Nuke to Muster.
Change: server, username and password to your muster server account.

Usage: If you run the script with nothing selected it renders all Write nodes.
Otherwise it renders the selected Writenodes.

Remember to save your script before submitting.

import re, os
import nuke

server = "address"
username = "username"
password = "password"

def madSubmit():
    a = nuke.knob("first_frame")
    b = nuke.knob("last_frame")
    start = int(a)
    end = int(b)
    incr = 1
    _range = a+","+b
    r = nuke.getInput("Frames to render:", _range)
    if r is not None:
        r = re.sub("[,|-|/]", " ", r)
        t = r.split()
    else:
        return
    if len(t) > 0:
      start = int(t[0])
      end = start
    else:
        return
    if len(t) > 1: end = int(t[1])
    if len(t) > 2: incr = int(t[2])

    cmd = '""%s\\Mrtool.exe" -s %s -u %s -p %s -b -pk 10 -e 28 -n %s -sf %i -ef %i -bf 1 -st 1 -f %s' % (os.getenv("MUSTER", "Failed"), server, username, password, os.path.basename(nuke.value("root.name")).split(".")[0], int(start) ,int(end), nuke.value("root.name"))

    writeNodes = [n for n in nuke.selectedNodes() if n.Class() == "Write"]
    if writeNodes:
        cmd += ' -add "-X '+','.join([node.name() for node in writeNodes])+'"'
    cmd +='"'
    print cmd
    os.system(cmd)

This is a little function that takes a number and adds padding to it.

global proc string padNumber(int $number, int $length){
	string $paddedString = string($number);
	while(size($paddedString)<$length)
		$paddedString = ("0"+$paddedString);
	return $paddedString;
}

Example:
padNumber 55 4;
// Result: 0055

This is a simple Nuke Gizmo that is similar to the Split Toning feature in Adobe Lightroom.

I wrote this script after a very buggy period of Maya use. After i found myself digging around in the temp directory, searching for the recently crashed file.

I run it at Maya startup so that it’s always there and up to date.
