About this Mod

Seamless

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!

Frequently Asked Questions

Does Seamless need to be installed on the Minecraft server?

No. Modrinth marks Seamless as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Seamless require?

Use a file for fabric, forge, neoforge and your exact Minecraft version. Supported versions include 1.21.5, 1.21.4, 1.21.1. Files for different loaders are not interchangeable.

Seamless is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
