ContinuityHorizon

Continuity-style connected textures for Horizon, as a native mod: blocks of the same kind join up into one surface instead of showing a border on every block. It works with the game's own textures; no resource pack needed.

• Glass and stained glass (all 16 colours and tinted glass): the frame between two blocks of the same glass goes away, so a window is one pane with one frame round it.
• Glass panes: the same, between panes of the same colour.
• Bookshelves, cut and chiseled sandstone (red too): joined left and right into one long shelf or band.
• Sandstone and red sandstone: a wall or pillar loses the band between its blocks; the top row keeps it.

Options > Mods > Connected Textures turns it on and off, and each part on its own; the world is redrawn at once.

Inspired by Continuity (MIT), recreated for Horizon.
