Hello, Im doing an art test and my task is to make a scene using free assets and then send the scene to them. But my whole project folder has around 2GB. If Im going to send them only my one scene file *.unity, will It start to download all the assets when they open it?
No, it will not. Assets once imported into a project get a local unique AssetID. The scene will reference those assets based on the assetID. So you have to include them as well. You can export your scene as package. Make sure you export the dependencies as well.
