Dumbass. You dont need any plugin or download. Just a model with a script in it, where you put in the bl save and it converts it on the spot.
I want to make it a plugin, it's more proper and will probably work easier, how am I going to give that plugin to other people? They will magically get it from my computer? That's what I have been trying to explain to you, I'm definitely not making it a model because that will lose ownership in literally a matter of days, little Roblox cigarettes will go and say they made it, even if I go and try and encyrpt the script they always find some bullstuff way to steal stuff.
