The more observant of you will see that I stole this from Trevor’s plugin post. But the short of it is that the “soon” has arrived. This is a bug fix to the FBX 2011 series, the main issue addressed for SDK users is the tessellation in KFbxGeometryConverter::TriangulateMeshAdvance()

===============================================================================================

FBX 2011.3.1, the follow-up bug fix release to FBX 2011.3, has been released on http://www.autodesk.com/fbx. This release addresses a small number of critical issues that some users have identified to us.  There are no new features in this release; we’re working on those for a future release.  For those of you who would like to participate in that beta project, please contact me at fbxbeta @ autodesk.com for further information.  If you have already been a beta member for previous projects like “Turnpike” and “Arsenal” (FBX versions 2011.1 & 2011.2), then you will be contacted sometime next week regarding the startup of the project.

This release includes FBX 2011.3.1 Plug-ins for the following products:
Autodesk 3ds Max 2009 (WIN 32/64-bit)
Autodesk 3ds Max 2010 (WIN 32/64-bit)
Autodesk 3ds Max 2011 (WIN 32/64-bit)
Autodesk 3ds Max Design 2010 (WIN 32/64-bit)
Autodesk 3ds Max Design 2011 (WIN 32/64-bit)
Autodesk Maya 2009 (WIN 32/64 bit / MAC / Linux 64-bit)
Autodesk Maya 2010 (WIN 32/64 bit / MAC / Linux 64-bit)
Autodesk Maya 2011 (WIN 32/64 bit / MAC / Linux 64-bit)

The following downloads are also available:
Autodesk FBX 2011.3.1 Converter (WIN / MAC / Linux)
Autodesk FBX 2011.3.1 Software Development Kit (WIN / MAC / Linux)
Autodesk FBX 2011.3.1 Extensions Software Development Kit (includes published reader/writer source code) (WIN / MAC / Linux)

FBX 2011.3.1 files are compatible with our currently available FBX 2011.2 plug-in for QuickTime, so there was no need to provide a 2011.3.1 FBX plug-in for QuickTime.

What’s new in FBX 2011.3.1?
Please refer to the plug-in’s readme files for information regarding bug fixes in this version.

These two bug fixes are worth pointing out to Area members:
1. In Maya, objects being merged into a scene would be merged according to name and not the dag path.  This was a regression in behavior, compared to previous releases of FBX.  This has been fixed in 2011.3.1; now the dag path will be considered during merge operations.

2. We have improved our triangulation algorithm in FBX SDK version 2011.3.1.  This triangulation algorithm is also being called by our COLLADA exporter option, “Triangulate”.

Thanks and enjoy!

1. NEW AND DEPRECATED FEATURES
------------------------------

1.1 New Features

No new features in this release.

1.2 Deprecated Features

* All functions related to local and global “state” in the KFbxNode
declaration were removed since their implementation didn’t work anymore
since the last release. They should have been set to deprecated within
the header files, but they were forgotten.

2. FIXED AND KNOWN ISSUES
-------------------------

2.1 Fixed Issues

* The unroll filter was inconsistent when applying its process on curves
data, this has been corrected.

* Fixed a crash in the function EmulateNormalsByPolygonVertex.

* Visual Studio 2010 builds were reporting missing PDB files, this has been
corrected.

* Importing various .OBJ file sometime resulted in much more vertices, this
is now working as intended.

* The mesh triangulation method has been re-written for a much more robust
algorithm. Now it can handle non-concave shapes. The method can be called
using TriangulateMeshAdvanced.

* A conversion error from Euler to Quaternion has been corrected, it is now
much more robust for corner cases.

2.2 Known Issues

* The static library version of the FBX SDK only ship with SECURE_SCL=0 for
the moment. In the next major release, we intend to change this back to
the default value, which leaves it defined to 1.

Robert Goulet, FBX Dev Lead

The static library version for Windows 2011.3.1 does not contain the lib files for 2011_3_1, and all the samples are configured for the dynamic version.
