Hello! I wasn't using sketchfab a whole lot, but recent addition of the store made me interested.
However, one thing I'm wondering - how exactly do you add LOD's to your model on sketchfab? I couldn't find any instructions for that in "help center", except that one line that "you can add LOD's".
And it's kinda a big deal, because not every game engine has an auto-LOD feature like UE4 does, so in order to upload quality models, they must have LOD's included.
