Yes, they skipped 9 for technical reasons.
if its intel integrated graphics, you wont get shadows with your shaders
Intel drivers recently got an update so some can run shaders with shadows.
OP, please open Blockland, join any server, then switch your shaders to something like medium then post a console.log found in your default Blockland directory. If you use Steam then Steam/SteamApps/Common/Blockland if you use the launcher then Documents/Blockland
