Hopefully this is useful to people exporting stuff out to UDK from Maya. You can batch export your models which take the geometry name. Currently trying to figure out an elegant solution to renaming/checking again if name is correct. So make sure to name your objects otherwise you are gonna get pSphere9000 :P Anywho here it is.

Download Here.

Installation:
1. Download the .mel file.
2. Place it in your My Documents/maya/scripts folder.
3. Re-start Maya (or type rehash in command line) and type fbxExporter; in the MEL command line to launch the tool.
4. Make shelf button or add to marking menu's for profit.

TO DO:
- Implement ASE batch export
- Implement quick pivot changes as second tab.
- Implement some sort of quick export options like recently used paths/last used options.

Cheers and feedback is always appreciated

EDIT: O and big thanks to MoP. Used his multiObjTool script to learn. Thanks MoP

    Hey haiddasalami! Cool idea, this is definitely useful for working with UDK. :)

    One thing I might suggest is that you investigate Sets with custom attributes on them (eg. export path) so that if the user exports a selection of multiple objects to a specific path/filename, you then store those objects in a new Set, name the Set to match the filename, and store the path in a custom attribute.

    You could also use Locators in sets to allow users to set custom pivot points for export - then the script can simply offset the contents of the Set to make the Locator be at world 0,0,0, resulting in a nicely aligned set of objects in a single FBX file.

    This'll mean you can have scenes containing multiple objects in any heirarchy, all being exported to custom FBX files with any offset or any sub-grouping of objects, which is much more flexible than simply outputting each object to its own filename.

    ... hmm, I should probably get around to upgrading my old scripts :)

    Keep up the good work, I'm sure a lot of people will find this handy, and no doubt have other good ideas to improve it too! :)

    Thanks so much for the useful tool. Did you happen to work out how to keep the object's original location in world space upon exporting? Thanks again.

    Feel free too :) Also got the script updated to move back to its original location. Updated the original post with download too. Also looking back at the code, center pivot unchecked never worked haha so fixed that too.

    thanks Lamont. Seen a bunch of scripts that do it that way. Gonna try and re-write this script with set functionality like MoP suggested and move this to python and maybe learn some pyQT along the way. Let me know what you cook up with it :)

    I did some digging on what MoP said about custom pivots. I think if you do export scene (maybe not object) while the objects are in a group it will retain the proper offset (world/local). Use the pivot for the group center.

    Just a thought.

    Very cool, I can see this being very useful in the near future :)

    One thing I'm interested in, and not sure how you would go about this, is some kind of system for exporting objects with collisions as well. I'd guess something like taking a mesh's name and allowing an option for user-input prefixes to get exported with it, like UCX_ or whatnot.

    I have my UCX rename script I can toss in, then you can mod how you need. I just updated it to do just simple rename as well. Need to update my random select as well.
    global proc UCXnameUI()
    {
    string $window = `window -title "UCXNamer v.0.9"`;
    string $meshName;
    string $meshSuf;
    string $meshLetter;
    rowColumnLayout -numberOfColumns 2 -columnAttach 1 "right" 0
        -columnWidth 1 100 -columnWidth 2 250;
    //text -label "Name" ObjectNM;
    text -l "Object Name" -al "left";
    textField -text $meshName ObjectNM;
    text -l "Suffix" -al "left";
    textField -text $meshSuf ObjectSUF;
    text -l "Prefix" -al "left";
    textField -text $meshLetter ObjectPRE;
    button -label "Rename" -command "nameUCX";
    //button -label "Rename" -command "nameUCX";
    showWindow $window;
    }
    UCXnameUI();
    
    
    global proc nameUCX()
    {
    $meshName = `textField -q -tx ObjectNM`;
    $meshSuf = `textField -q -tx ObjectSUF`;
    $meshLetter = `textField -q -tx ObjectPRE`;
    
    
    	string $sel[] = `ls -sl`;
    	string $curSel;
    	int $i = 1;
    
    	for( $curSel in $sel )
    	{
    		string $col = ($meshLetter + $meshName + "_" + $i);
    		print( $col + "\n");
    		string $curSelShapes[] = `listRelatives  -shapes $curSel`;
    		rename $curSelShapes[0] ($col + "_"+ $meshSuf);
    		rename $curSel $col;
    		$i++;
    	}
    
    }

    First, thank you so much for this awesome script !
    I'm gonna use it everytime now ! :)

    Some questions/suggestions :

    -What does mean "Preserve Mesh Input Connections" ?

    -It's possible to get a message box error when you hit "export" without tipping before an output path ? I know, it's stupid, but sometimes I forgot and *bam*, I got a Maya crash. :poly142:

    -Does this exporter support the LODs ? Like explained on this UDN page : http://udn.epicgames.com/Three/FBXStaticMeshPipeline.html#Static%20Mesh%20LODs ?

    -It's also possible to export the full scene if when don't select anything ?

    [EDIT]
    I guess, something like that :
    if ($sizeSel == 0){
            warning("Nothing is selected");
            confirmDialog -title "Error" -message "Nothing is selected" -button "OK" -defaultButton "OK" -cancelButton "CANCEL";
        }
        else if( $sourcePath == "")
        {
            warning("No output path defined");
            confirmDialog -title "Error" -message "No output path is currently defined" -button "OK" -defaultButton "OK" -cancelButton "CANCEL";
        }
    

    But I don't get the message, only an error in the comment line of the maya window :
    "//Error: Cannot find procedure "fbxExport()"."

    Good to see people getting a use out of this :)

    @Froyok: Thanks for bringing those errors up. I swear I thought i put in checks but probably removed them at some point. Will fix those up today. Regarding preserve mesh input connections, if something is grouped, the fbx exporter will export that group as one mesh.

    LOD's should be doable. They just need an option ticked, which reminds me, anyone have any experience exporting animation with FBX? Do you just tick the animation box when exporting it or is there something else too? Regarding the full scene export, is there a functionality you want when nothing is selected?

    @S2Engine: Trying to think of a friendly way to integrate collision export as well. MoP's set method would probably be my best bet.

    @Lamont: thanks for that UCX code, will probably use it/tweak it to get what I need.

    Guess I have a lot of coding to do haha :)

    I only have a mite of experience with animation to FBX (meant for Unity), but I haven't had much issues with just ticking the animation box. I've worked with people who tried the same thing and didn't get proper results, and the only difference we found was in which version of FBX exporter we used, as they were on 2009 when I was using 2011. I also mostly only dealt with getting everything baked to individual keyframes, as there were always errors when trying to output with curves and such.

    Hey haiddasalami! love your scrip! I've been using it to for the past week and didn't have a problem, but for some reason starting yesterday, when ever I use it, it wont export all the objects selected in my scene. only part of my selection will be exported. Strangely though, if I export one by one using your script, I don't have a problem. What am I doing wrong? I am using Maya 2014, just so you know.

    Thanks a bunch for the awesome script!

    Hey not sure about this. Will try it on 2015 but are you using LT by any chance?

    EDIT:Tested in 2015. Didnt notice a slow down.

    Thanks! Not sure what it is. Mind hosting the ma/mb file somewhere to test or showing what the outliner looks like.

    Absolutely! what would be the best way to share my file with you? Could Email work for you? I would rather not share it publicly if possible.

    And on further examination, I notice it seams to fail on a specific items: it will go troughs the list of items in my Outliner in order (First selected to last selected) but the moment it selects a specific object, it will move it (if i ticket center to grid) but not export it. And to correct what I said earlier, even if I select the item alone, it will NOT export it as normal. So maybe its something wrong with my model but I didn't treat it any differently then the others.

    On an other note, changing the name of the problematic item seamed to fix it, but how would that make any sense?

    Ok, Dropbox's security settings are pretty shitty now wow! But ill be hosting it temporarily There for this issue. Let me know when you have your hands on it so I can remove it.

    So the problematic item is Skeleton_Pelvis

    Its weird that changing the name seams to fix it, its not like Maya would even allow me to have two items named the same.

    Whoops sorry. Stepped away from desk. You can remove it now. Will take a look. Possibly conflicts with shape name.

    EDIT: Yup its name conflict. So inside my code I call Maya Short Name instead of Full Name (was a noob back then XD) so it trys to select Skeleton_Pelvis but there is a skeleton pelvis inside skeleton_small and one in the root of the scene.

    Just open up the script and copy and paste that in. Should work exactly the same. Seems when two conflicts like that happen. Maya forces the second mesh to take the long name of the mesh. Ill update the dropbox mel file when I get back home. Hope that helps :) Weird reading code I wrote like 3 years ago haha

After copying the .mel file to the scripts folder and adding the script to the Shelf, the UI window doesn't launch nor do I get any warnings/ errors. Is there anybody who has tested this script with Maya 2017 and can offer some advice on how to get this to work. It will be the best thing to have for my Project!!

    I cant seem to get this to work, I copied the script above, saved, pasted into maya, saved it as mel, put it in my scripts folder, made shelf icon, and when I restart and click the button all it does is echo the code in my script editor but nothing happens.

    Hey man! I just wanted to say that I've been improving my workflow on Unity and this was perfect! I've been searching for an script that exports locators (so I can have multiple objects exported as one) and this one is simple and perfect. Thank you again!
