Seamless
With Seamless installed, the outline around a bed, door or double chest is drawn as one shape instead of two separate boxes.
What it does
Seamless connects the outlines of blocks that occupy two or more spaces, such as doors, beds and double chests, so each combined block shows a single outline. The mod runs on the client only, so a server does not need it and players can join a server without installing it. Seamless requires Architectury API and is published for Fabric, Forge and NeoForge across 17 release versions, 1.18 – 1.21.5.
Its behavior is defined through data-driven resource packs rather than code. A pack can add connected outlines for any combined block, regardless of its size, and a pack author can make compatibility for other mods without changing the mod itself. Seamless is not open source; it is released under All rights reserved. Source code, an issue tracker and a wiki are linked from the project, and the wiki covers how to write these packs.
Key features
Connected double-block outlines
Beds, doors and double chests are drawn with one outline covering the whole combined block.
Large plants
Tall grass, peonies and pitcher plants get a single outline across their two-block height.
Small dripleaves and tall seagrass
Small dripleaves and tall seagrass are outlined as one shape rather than per block.

Pitcher plant crops are covered by the same connected outline as other double plants.
Support for other blocks

Use cases
Building with double blocks
Builders who place many doors, beds and chests can read the outlines of whole blocks at a glance.
Adding compatibility through packs
Modpack makers and resource pack authors can extend the outlines to additional blocks by writing data-driven packs.
Who it’s for: Players who use decorative or building mods with double blocks, and pack makers who want outlines for blocks added by other mods.

What the author says
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. This means that you can add compatibility for any mod yourself, through simple resource…
