CADuvFIX - SOP : Fixing UV's auto generated by Moment of Inspiration, when exporting CAD/Nurbs model using .FBX. It does require MOI 5.0 beta (dec), as this last version generates the appropriate surface ID.
MoI 5.0 exports intrinsic uv's coming from the Nurbs surface, so every surface has normalized UV's in a 0-1 space. They are hardly exploitable in that arrangement.
Beside some surface have inverted projection
Labs calculate uv distortion is handy to visualize those distortions, but won't fix anything.
CADuvFIX will go a bit further, and generate the proper scale fix needed to minimize those stretching and also fix inverted projection.
The orthogonal / axis aligned nature of those UV's makes the packing efficient.
Different showcases :

I also include a test mesh generated by MoI to test the tool.
