Unable to download it when coming ingame? Download the pack one here and install it in your Minecraft folder.
You will occasionally need to update this pack!
1. Once the download has finished, go to your downloads folder and copy the sspackv1.4.zip file.
3. If on Windows, click the Windows key and R key at the same time and search for %appdata%. A bunch of folders will then show on your screen. If on Mac, open finder and use shorcut Command+Shift+G then paste ~/Library/ as your search directory then Application support > Minecraft > Resource packs
4. Open the .minecraft folder then open the resourcepacks folder and paste in the sspackv1.3.zip folder you copied earlier.
5. Launch the game and go into Options > Resource Packs then transfer the sspackv1.3.zip texture-pack into the Selected Resource Packs side. Click done once that is complete.
