hideLidWalls and hideBasWalls only works when showSideBySide = false, contrary to documentation.

In code comment , it says only if preview and showSideBySide=true

hideLidWalls              = false;      //-> Remove the walls from the lid : only if preview and showSideBySide=true 
hideBaseWalls             = false;      //-> Remove the walls from the base : only if preview and showSideBySide=true
