Hello
a month ago I sent Brad Bolthouse an FBX file , complaining that his converter does not work
This week Brad sent me a new version of his converter
The problem has been fixed, at least for the files in my hands
I think that this news can be of help for those who, like me , have been struggling with this (bloody 
) file format
as well as to thank Brad for his professionality
Yup, Brad’s a great guy and UU3D is a great product. I haven’t used it in a couple years now that I’ve been (mostly) on a mac. Glad to hear he sorted this out.
Ultimate Unwrap has proven to be one of my most reliable format conversion tools over the years. Covered my back when using Blitz3D, Ogre and several other engines. Good to hear that FBX support works too.
I use 3dsmax so don’t have much need for Unwrap 3d normally, but it’s been a godsend on occasion 
UU3D saved my ass when I had to do a walkthrough with Blitz3D and XSI as modelling/rendering app. And he was really fast in enhancing his plugins for the Blitz3D<->XSI pipeline.
