Connected Textures Wiki

Connected Textures (CTM) is a client-side mod that makes adjacent blocks of the same type blend into one continuous, seamless surface instead of showing a repeating grid of individual block faces. A wall of glass becomes a single clean pane; a row of bookshelves becomes one long shelf; large sandstone or stone-brick structures lose their tiled look.

It works by reading connection metadata that resource packs supply, then choosing the correct edge/corner texture for each block based on its neighbors. Because it is purely visual and client-side, it is safe to use on multiplayer servers - it changes nothing about the world, only how blocks are drawn on your screen.

1. Load into a world. Blocks that ship with built-in CTM support (and any blocks covered by a CTM-enabled resource pack you have active) will immediately connect.
2. To get the most out of it, add a resource pack that includes CTM data (see the Using CTM Resource Packs section) and activate it in Options > Resource Packs.

No world changes are made, so you can add or remove the mod at any time.

For each block face, CTM looks at the neighboring blocks and picks the texture variant that fits:

• a face with no matching neighbor uses the standalone texture,
• faces along an edge use edge textures,
• inside corners use special inside-corner textures,
• fully surrounded faces use the seamless "middle" texture.

The available connection styles include:

• Full / CTM - connects in all directions for a fully seamless surface (best for glass, large walls).
• Horizontal - connects only left/right (e.g. bookshelves, logs).
• Vertical - connects only up/down.
• Edge / inside-corner - refine how the seams and corners are drawn.

The mod assembles these tiles on the fly so the result looks like one big texture rather than many small ones.

Connected Textures reads CTM metadata from resource packs. A pack enables connection on a block by providing a .mcmeta connection file (CTM properties) alongside the block's texture, telling the mod which connection style to use and which extra tiles to draw.

To use them:

1. Download a resource pack that advertises CTM / Connected Textures support.
2. Drop it in .minecraft/resourcepacks and enable it in Options > Resource Packs.
3. Blocks the pack defines connection data for will now blend together.

If you make packs yourself, supply the CTM .mcmeta/properties metadata for each block you want to connect and choose the appropriate connection style (full, horizontal, vertical, etc.).

Connected Textures has an in-game configuration to control the effect:

• Toggle CTM on/off globally if you want to compare or disable the effect.
• Toggle inside-corner rendering - some players prefer connections without the extra inside-corner tiles for a flatter look.

Open the in-game config screen to adjust these. Because everything is visual, changes apply immediately without touching your world.

My glass/bookshelves aren't connecting. The block needs CTM connection data. Vanilla blocks only connect if you have a CTM-enabled resource pack active that defines them - enable one in the resource-pack menu.

Does this work on servers? Yes. It is entirely client-side and visual; the server does not need the mod and nothing in the world is altered.

Can I use it with shaders / Optifine-style packs? Connected Textures provides its own CTM implementation; use packs built for it. Behavior with other texture-connection systems depends on the pack.

It hurts my FPS. Connecting textures adds some render work. Toggle inside-corner off or disable CTM for specific heavy builds if needed.
