To get the original resource pack, go to https://jragoncommands.weebly.com/tempests-box.html and scroll down to 'DOWNLOAD RESOURCES'. Click that, and unzip the file you get. Now either A. You will get 3 files, one of them being resources.zip. That is the resource pack. OR B. You will get a folder. In there is the resources.zip.
