Opaque Doors! is a resource pack that basically replaces the transparent parts of doors in Minecraft with color. Meaning, holes in doors are removed.
It was made for my in-development map "One-Way Finish Maze". Users of this RP will not be able to see if the door leads to a dead end or a game over or not. But, I decided to change the other doors and release it to teh public.
It was made using ResourcePack Workbench by MightyPork.
