Nukeでchannelsがalphaでwhite_clampが無効になっているGradeノードの名前を返すスクリプト

search_error_grade.py

import nuke
def search_error_grade():
    error_grade = []
    for n in nuke.allNodes("Grade"):
        if(n["channels"].getValue() == 4.0 and n["white_clamp"].getValue() == 0):
            error_grade.append(n.name())
    return error_grade


print(search_error_grade())

より汎用的なやつ（Gradeオブジェクトを返す）

import nuke
def search_error_grade():
    error_grade = []
    for n in nuke.allNodes("Grade"):
        if(n["channels"].getValue() == 4.0 and n["white_clamp"].getValue() == 0):
            error_grade.append(n)
    return error_grade

for grade in search_error_grade():
    print(grade.name())

エラーを自動修正(white_clampをオン)

import nuke
def search_error_grade():
    error_grade = []
    for n in nuke.allNodes("Grade"):
        if(n["channels"].getValue() == 4.0 and n["white_clamp"].getValue() == 0):
            error_grade.append(n)
    return error_grade

for grade in search_error_grade():
    grade["white_clamp"].setValue(1)
