AndrewHazelden / padded_frame_number.mel

Last active December 9, 2015 11:39

A MEL script for generating a frame padded number. In this case the source value that is frame padded with leading zeros is the start frame value from the Maya Render Settings window

	// Add zero digit padding to an int value
	global proc string pvr_zeroPadding(int $num, int $padding){
	// Tip from the blog post: http://ldunham.blogspot.ca/2012/01/melpython-adding-number-padding.html

	int $lengthNum=size(string($num));
	string $padString;

	if($lengthNum<$padding){
	for($i=0;$i<($padding-$lengthNum);$i++){
	$padString=$padString+"0";

AndrewHazelden / progress_bar_demo.mel

Last active February 4, 2022 20:19

A MEL script for updating a progress bar as a task is running. If the escape key is pressed the task stops and the progress bar is hidden.

	int $startFrame = `getAttr "defaultRenderGlobals.startFrame"`;
	int $endFrame = `getAttr "defaultRenderGlobals.endFrame"`;

	// The $frameStep variable is used to implement frame skipping using the "By Frame" render settings attribute.
	int $frameStep = `getAttr "defaultRenderGlobals.byFrameStep"`;

	string $progressText = "";

	if($startFrame != $endFrame){
	// Show a rendering progress bar

AndrewHazelden / print_env.mel

A MEL command for checking what the operating system's environment path variable is when launching child processes using system() on Windows.

	// Windows
	system("echo %PATH%");

	// Mac & Linux
	system("echo $PATH");

AndrewHazelden / print_env.py

Last active December 9, 2015 11:36

A Python script to check the system's environment path variable

	import os
	print '[System ENV PATH] ' + os.environ['PATH']
	# Result: [System ENV PATH] /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin

AndrewHazelden / check_batch_mode.py

Last active May 9, 2023 07:38

A python script to check if Maya is running in Batch mode or with a GUI

	# Check if Maya is running in Batch mode or with a GUI
	# A return value of 1 means Batch Mode, 0 means GUI mode
	def checkMayaGuiBatchMode():
	"""
	Maya tip on detecting Maya Batch mode is from Michael Scarpa's blog post "MEL Sillyness":

	"""

	# Check if Maya is running in batch mode or with a GUI
	import maya.OpenMaya

AndrewHazelden / file_exists.py

Last active December 9, 2015 11:36

Use Python to check if a file exists on disk

	import os

	# File to check
	mxsFilePath = 'C:/Program Files/Next Limit/Maxwell 3/scripts/stereo/CubeX.mxs'

	# See if the file exists
	if os.path.exists(mxsFilePath):
	print('[MXS File] ' + mxsFilePath)
	else:
	print('[MXS File Not Found] ' + mxsFilePath)

AndrewHazelden / check_camera.py

Last active December 9, 2015 11:37

Use Maxwell Render's PyMaxwell tool to check the active camera's name and resolution settings

	from pymaxwell import *

	# Maxwell .mxs scene file
	mxsFilePath = 'C:/Program Files/Next Limit/Maxwell 3/scripts/stereo/CubeX.mxs'

	# Load the mxs scene
	scene = Cmaxwell(mwcallback)
	scene.readMXS(mxsFilePath)

	# Read the active camera's name and resolution settings

AndrewHazelden / date_time.py

Last active March 1, 2016 22:23

Use Python to generate a date and time stamp as a string

	import datetime

	# Get the current time
	now = datetime.datetime.now()

	# Make a note of the date and time in a string
	# Example: 2015-12-05 12:34:24 PM
	textDocument = '# Scene Generated: ' + now.strftime('%Y-%m-%d %H:%M:%S %p') + '\n'

	print textDocument

AndrewHazelden / get_filename.py

Last active December 9, 2015 11:37

Use Python to separate a filepath into the base directory, the file, and the filename without an extension

	import os

	mxsFilePath = 'C:/Program Files/Next Limit/Maxwell 3/scripts/stereo/CubeX.mxs'

	# Find out the current scene file
	dirName = os.path.dirname(mxsFilePath)
	sceneName = os.path.basename(mxsFilePath)
	scenePathNoExt = os.path.splitext(mxsFilePath)[0]

AndrewHazelden / maxwell_color_space.py

Last active December 9, 2015 11:40

Use Maxwell Render's PyMaxwell tool to read the active color space

	# Get the Color Space
	# Example: scene = Cmaxwell(mwcallback); colorSpace = mxa_getColorSpace(scene)
	def mxa_getColorSpace(scene):
	colorSpace = ''

	colorSpaceValue = scene.getColorSpace()
	if colorSpaceValue == COLOR_SPACE_SRGB:
	colorSpace = 'sRGB IEC61966-2.1'
	elif colorSpaceValue == COLOR_SPACE_ADOBE98:
	colorSpace = 'Adobe RGB'
