Model storage location

Hi all, I'm new here coming from unity and unreal engine, getting to learn the editor a bit. I'm not too sure if it's been discussed, but how does the editor handle the models that you get off of the library? is it cached on the local machine? or does core keep a record of it on their servers? How much hard drive space could a game with let's say 1,000 models in scene use?

thank you for any input

Everything is already in the client installed on your computer. Each game doesn't install it's own assets independently, they all use the same assets. The core game files themselves are basically a pair of text files, one of which lists the assets used, the other the instructions for what to do with them, such as resizing, texturing, and placement.
