*which version of FC?*
have you read my mail? I told you to export after select shaded view... 
but if you don't want to learn how to use FreeCAD or just listen, nobody 
can force you...

FYI here the file exported from FC with the method I told you to use are 
all fine and without any problems (as displayed in view3dscene)
name-fc.wrl -> means freecad wrl standard exported
name-fc-ksu.wrl -> means freecad StepUp VRML macro exported

IGES is a worse source for 3D MCAD compared to STEP, but anyway here the 
file exported
https://github.com/easyw/kicad-3d-models-in-freecad/raw/master/test-vrml/assieme_leg-fc.wrl

those, you have chosen, are much more complex 3D models than what 
normally kicad should manage

IMHO I don't think so

Anyway, this discussion is getting a wrong direction...
