I don’t see any benefit from models being locked upon inserting from the catalog. Especially for newbie developers who are brand new to the engine and don’t know how to unlock models.
You’re almost always going to reposition x model upon insertion. I think it would be a good idea for models to by default be unlocked from free model catalog insertion. Thanks!
Better: Make the PrimaryPart auto unlocked, at least. This would ensure things that probably should be locked stay locked, but if a model maker puts a sensible primary part, it should be fairly obvious where to click a model to select it, without unnecessary model property changes elsewhere.
What happens if the model in question requires certain parts to be locked for script purposes?
I can’t think of any reason why it would need to be locked for a script? But even so they could just lock x parts themselves.
