Sometimes, we need to load 2D/3D assets at runtime in our unity application. We can do this by saving it into the Resources folder in the unity editor and they’ll be availables after compilation to load them at any time. The Asset Bundles is an option to store assets to load them from a hard disc, an sdcard or, even, a server location. However, all these options need to use unity editor and, the asset bundles case, Unity Pro Edition is required.
