How to measure the time of a Maya script?

阅读更多关于 How to measure the time of a Maya script?

问题 I have several methods implemented in MEL, and I would like to measure its performance. Is there any way to measure execution time of a fragment of code? Something equivalent to "getCurrentTime" in other languages. 回答1: the timerX() command will give you seconds since Maya was started, so you can grab that and do the math: float $start = timerX(); 回答2: Timer // Example 1: Simple timing // $startTime = `timerX`; // code that is being timed $totalTime = `timerX -startTime $startTime`; print (

How do I execute Maya script without lauching Maya?

问题 For example, I want to launch a script that creates a poly cube, export it to .stl or .fbx from the command line. I can do it in Python by using the Maya standalone but it cannot handle exporting to other formats than .ma apparently 回答1: Why of course you can. Here's how you'd do exactly that (for FBX): from os.path import join from maya.standalone import initialize import maya.cmds as cmds import maya.mel as mel initialize("python") cmds.loadPlugin("fbxmaya") my_cube = cmds.polyCube() cmds

Maya - Querying previous render information

阅读更多关于 Maya - Querying previous render information

Does anyone know whether its possible to query the render time of the last render in maya via python or mel? Render time is stored in the render viewer window in the form of a string at the bottom of the image, I would like to access this time and retrieve for later use - is this possible? Thanks I know of no way to query it directly, but this solution works: Put the following in your Pre Render MEL (from the Render Settings): python "global last_render_time;import time;last_render_time=time.time()" Expanded for readability: global last_render_time # not needed when in module import time last

How to execute a Maya MEL procedure at regular intervals

阅读更多关于 How to execute a Maya MEL procedure at regular intervals

问题 I would like one of my Maya MEL procedures to be executed every x seconds. Is there any way to do that ? 回答1: The mel setup would be scriptJob -e "idle" "yourScriptHere()"; However it's hard to get the time in seconds from Mel - system("time /t") will get you time to the minute but not to the second on windows. In Unix system("date +\"%H:%M:%S\"") would get you hours, minutes and seconds. The main drawback to scriptJob here is that idle events won't be processed when the user or a script is

问题 I'm using the amazing Sublime Text 2 to write MEL (Maya Embedded Language) scripts for Maya, but it has no syntax highlighting for MEL. Right now I force it to interpret the text as Perl, which does an OK job, but its far from perfect. It would be handy to add Maya's commands. Does anybody know how I would create a syntax highlighting set for Sublime? 回答1: I have been using a MEL textmate bundle I found on github. I forked it, added some snippets and tweaked the language a little. The
