This wasn't happening with older versions of Reality Converter... I open a GLTf file created in Cinema 4D and all corners are smoothed, completely transforming the object's geometry. Reality Converter was a very useful tool for quick object testing: save in USDz and a look using iPhone, unfortunately is this smoothing happens this is not usable anymore. Does anyone know why this is happening and how to turn it off?
This is a screenshot from C4D
And this is the same object imported in Reality Converter
