About this project
What does Seamless add?
A client-side data-driven mod that connects the outlines of double blocks, like doors and beds. The mod is entirely configurable through resource packs, which allows any combined block, no matter its size, to have one big outline.
Connected outlines for:
- Doors
- Beds
- Double Chests
- Large Plants, like Tall Grass, Peonies and Pitcher Plants
- Small Dripleaves
- Pistons
- Tall Seagrass
- Pitcher Plant Crops
Most modded Plants, Doors, Chests and Beds should work too!
It's completely data-driven!
This means that you can add compatibility for any mod yourself, through simple resource packs.
Want to learn how? Take a look at the Docs.
Built-in compatibility with:
- Create (Glass, Train, Brass, Copper and Andesite Doors)
- Supplementaries (Flax, Spring Launchers)
- Fast Paintings (Paintings)
- Farmer's Delight (Rice, Full Tatami Mats)
- Haunted harvest (Corn)
- Sleep Tight (Hammocks, Night Bags)
- Waystones (Waystones)
- Upgrade Aquatic (Bedrolls, Flowering Rush, Pickerelweed, Beach Grass)
- Biomes o' Plenty (Brimstone Clusters, Eyebulbs)
