So I'm making a better version of Build a Hide out and fight and I'm making a save system with Data Persistence and test it by building a castle. I made foundations for it and saved it and tested it and it worked. I finished my castle and it said it was too big to save. So I thought of data stores since they have no data limit. But I'm not quite sure how to save a whole model with Data Stores. All I know is how to save integers, strings, and booleans.
You can't directly save Instances to a DataStore.
To save data that can be used to to "rebuild" the creation later, you have to do something called serializing the data. There are multiple scripts already made to do this, and a few I think are on Free Models.
I'm currently on mobile, making it difficult to write out code, so I'll write a serializer and deserializer pair of functions and add them to this post when I get home from work (About 6 hours from now).
