Sketchfab upload issue (smoothing)
Uploading the model into sketchfab doesn't seem to work as-is. None of the smoothing settings are being applied, even after enabling the normal map option and uploading the texture. Searching around people are saying that for smoothing to work with Blender models, we'll need to add and apply the Edge Split modifier. Is this the case? I tried using it on 1 section of my model and it does seem to help.
I don't remember Edge Split being mentioned at all in this series (though there was a quiz question related to this) and I don't remember seeing it in the modifier stack in any of the videos. Is this really necessary when exporting to sketchfab?
