Blender 2.79 breaks the export scale

[mafoo]

Using blender 2.79 causes all models to export with a scale of x100 this can manually be fixed by either using 2.78c to export, or adjust the scale factor on the mwmbuilder object

oh god I have the same problem on 2.79b

[stomachbrain]

check the settings of the blender add-on "import export FBX format"
In the Main category set the Scale to:
0.01 if the Blender units are "None".
0.01 if the Blender units are "Metric with Scale = 1"
1 if the Blender units are "Metric with Scale = 0.01"

OR

reload the add-on release 3.7.7 from the blender release 2.78b
