jbUnity Tools -- Maya tools script for Unity

A new version of my jbUnity Tools script is available. In a nutshell, it aids in the setup of the Maya scene (units, grid, camera) for the creation of Unity assets, also the conversion to meters. I've added some tools for positioning meshes and pivots as well as custom grid divisions, a unit calculator and a batch FBX exporter. Yes, it's still free.

Tested in Maya 2011, 2012 both PC and Mac (you may need SP1 or latest hotfix for the Mac version to work)

Includes:
* Quick switch between meters and centimeters
* Ability to change grid divisions on the fly and set custom divisions with multiple presets
* Tools to relocate pivots and/or meshes to common locations for level design
* Tools to create common reference objects
* A muti-field calculator for mm, cm, m, km, in, ft, yd, mi
* A batch exporter for the FBX file format that uses custom fbx preset files

Help file can be found here: jbUnity Tools Help

v0.91:
*BUG FIX: Float and int fields can now be updated with either numpad or regular enter keys

v1.00:
* FEATURE: Automatic loading of FBX preset file
* FEATURE: Basic UI coloring for clarity
* FEATURE: Auto load of custom references with buttons for each
* FEATURE: Batch export prefix/suffix option
* FEATURE: Stacking transform tool
* FEATURE: Keep custom grid color settings or use the jbUnity Tools grid coloring scheme

v1.20:
* UPDATE: Added support for Maya 2013

v1.25:
* Lots of code cleanup and bug fixes
* Exporter was rewritten and now includes options for Single, Hierarchy and Batch.
* Improved handling of FBX export preset files

v1.30
* Updated to work with Maya 2014

The FBX exporter now works intuitively in Maya like it does in other programs and no longer exports an entire hierarchy when you only want to export a single object. Use 'Export Single' to export a single mesh (even if it's part of a hierarchy), 'Export Hierarchy' to export a hierarchy of objects (even if they're nested in a larger hierarchy), and 'Export Batch' to export a list of selected objects (even if they're in a hierarchy).

Gonna give this a shot this weekend. I'm running 2010, so we'll see how it works. Definitely need some help exporting skinned meshes and anims into Unity, and I'm hoping this helps lol

 

Sorry, it won't work in versions prior to Maya 2011. Maya switched their UI system and some key functions in 2011+. Not impossible to get working by determining which version you're running and allowing for some alternatives, but I haven't had time to make that happen.

As a side note, the exporter uses an FBX preset file of your choice so it will work with animations, skinned meshes, whatever, but it's primarily been designed for level assets, especially modular assets. Gets me thinking about adding some features in support of the export of animations and skinned meshes. If anyone has any suggestions for features, I'm listening.

 

I'm running 2010.

The FBX presets usually include a deformed mesh, skins, blendshapes, etc

 

v1.20 now available.

* Resolves the UI issues with Maya 2013 yet maintains compatibility with Maya 2011 and 2012.

Latest version can be downloaded here.

Please let me know of any bugs/issues.

 

v1.25 of jbUnity Tools is available for download here: jbUnity Tools

jbUnity Tools is FREE.

Hi Josh,

I'd like to say that I find this tool extremely handy. I currently am encountering an error exporting via FBX in Maya 2013. I "Add" my assets to the "Objects to be exported" window, set my pivot position to "CB", press export and the following error appears:

line 907: cannot concatenate 'str' and 'NoneType' objects #

 

That's odd, definitely a Python error. Easy to fix, but I haven't had that happen locally. Are you on Mac or PC? You sure you had objects in the list for export? Were the objects still in your scene?

 

I am on a PC running Win7, the objects were in the list export and they were still in my scene after failed export. Attached is a screenshot and below is the Script Editor output.

This script looks extremely helpful... I really wanted to use the batch exporter function but I am getting the same error as dkertesz. Also on the same Maya version and OS as him plus the latest FBX exporter.

What I've noticed is that on startup it does have a "FBX Export Preset File", even though I have one in my user folder. So I manually tell the script where it is but on export I receive a different error below:

Here's what the command line says when I try to export two objects:
----- jbUnity Tools :: Export Batch -----
Exporting: ramp_smooth_14m_60deg
No parent found for ramp_smooth_14m_60deg
# Error: RuntimeError: file <maya console> line 908: Invalid file type specified: FBX export #

I am not sure why it's complaining about have no parent. Is there a specific hierarchy needed to objects to be batch exported as individual components?

 

v1.30 is out. Updated to work with Maya 2014

Now seeking feature requests for jbUnity Tools -- I'm planning an overhaul soon.

jbUnity Tools v1.40 is now available. Download at: CGARTISTRY

James: if you mean the position and orientation alignment, I added them back in for v1.40.

 

This tool rocks.

Initially I too had the:

- No parent found
- cannot concatenate 'str' and 'NoneType' objects #

error, however some sterling support from Josh via email discovered that I needed to set up a Maya Project for my scene as jbTools could not find the User FBX Preset file. Works great and thanks again Josh.

 

Glad it worked out. I will look into finding a better error log and solution for this problem. Thinking about a most common options export setting option that bypasses the fbx export preset file altogether (will keep the preset file as an option). This is what I use in The Rigging Toolbox as 99% of the time we all use common export settings from Maya to Unity.
