Create Txt File With Camera Names And Frames

Tags: #<Tag:0x007f192cf147c0>

rvr1982 2009-05-21 16:05:26 UTC #1

Hello,

I'm completely new to Mel-scripting
I'm trying to create a script that would, when launched, create a ".txt" file that would look like this :

CODE
scene01.mb
1
24
camera1
persp
top
front
side

The script should automaticaly find the name of the scene, the starting frame of the time slider, its ending frame, and the camera names of the scene, and list them in a txt file.

I found this code on 3Dfiggins.com
CODE
string $exampleFileName = "C:/NewTextFile.txt";
$fileId=fopen $exampleFileName "w";
fprint $fileId "First Line of Action\r\n";
fclose $fileId;

I think it should be possible with this script, but i don't know what should be placed instead of "first line of action" to get all the stuff i need.
Hope someone can help me out.

CODE
{
  string $path=file -q -sceneName;
  $shortName=basename($path ,"");
  $nfoFile=(match(".*[.]" ,$path)+"txt");

$fileId=fopen $nfoFile "w";

  fprint $fileId ($shortName+"\r\n");
  fprint $fileId (playbackOptions -q -min+"\r\n");
  fprint $fileId (playbackOptions -q -max+"\r\n");
  for ($item in ls -cameras)
    fprint $fileId (firstParentOf($item)+"\r\n");
  fclose $fileId;
}

Always the same guy who's saving my ass !

Thanks a lot, it works perfectly

That is definitely a way to go about it.

I am currently working on a much, much more sweet way of checking on scene data if you
own a Mac. (I'll post it when done)

I do a lot of scene gathering for it, and this script writes it out.
Scene name/location
Referenced filenames/locations
texture files/locations
Scene length, Timeslider range, render settings. The list goes on.

This saves it to a ".scinf" file (plain text) but you can just change the code to ask for .txt

If you want it I'll upload it when I get home.

Well i wouldnt actually do it thisway. I just answered the question it easier then the philosophical thinking of what to do. Thing is maya is perfectly capable of telling you the info you ask from command line and programmatically. So you dont need to have a file open to know its playback range cameras etc.

try mayabatch -? from yoru commandline. It knows to tell most of the data on your list

So you can just ask this info directly form the file without much special hustle with about the same overhead as reading the text file. So I for example have just implemented a windows shell extension for this data. This way its always visible in my file browser as a external column even if i fail to generate a file for it to use. Its always there.*

So theres NO RISK that the double bookkeeping isn't up do date because you dont use one.

texture files/locations

This is a tad bit tricky. As maya doesn't really know it. Not exactly anyway. One must do some assumptions that will fail spectacularly in certain special conditions. See maya can dynamically decide to load another file instead.

But yes these scripts already exist so don't bother to write them, just a waste of time. Download one form the repository.

but this is not something the average joe user would be capable of doing easily. Even many hardcore programmers would fail to get this done in a timely fashion. And no unfortunately im not the sole owner of the IP so i can not decide to share it (Its called work)

Well that sounds very interesting.

On the other hand, the poster didn't specify why they wanted it in the file.
I need to do something just like it for adding metadata to the end of a .ma file.
(It's used in conjunction with a snapshot of the scene at save time to produce a superfast Mac OSX "Quicklook" view of a scene file)

  There is plenty of data polled by this, if you wish more then by all means add it, and the same goes for subraction.

Referenced files/locations, texture files/locations, renderable cameras, image format, list goes on.

btw, In 8.5 SP1 I tried using mayabatch and it says not found, I also tried it as mayaBatch no dice.

Yes but maya has metadata fields natively in the file. They are not in the end f the file but up front in the start of the file. And its VERY easy to parse.

Yes under mac theres a link to special shell that loads the maya environment in. Presumably they didnt want to force the settings on all the possible variations fo shells you could use.

So the thing is mac doesnt know where to look for the commands by default. So just add the maya bin directories to your parth.

Err it doenst work when it comes to animated file sequences.!

I'm currently learning some java, and thought about a little application that would use these *.txt files to automatically generate *.bat files for rendering.
It just happens too often to start some renderings in the evening, and to discover next morning that part of your scenes did not rendered correctly, just because of some typing errors. This application should make me win some time at work...
It probably does already exist, but I consider this as a good training

cohphasor 2009-05-23 00:49:35 UTC #10

Excellent rvr!

Jooja, I do need to work on the script I referenced, and would love to have assistance on it.
Although it is closely related I imagine I should start a new thread?

   Thanks!

Um the java can simply just ask maya form commandline for the ranges on fly. That way you never need to worrry about the text files being off sync
