Void Floors
by JacobJake7
Void Floors places decorative End Portal blocks inside obsidian frames, so a walkable floor or ceiling shows the swirling starfield without teleporting anyone.
What it does
A player frames an opening with obsidian, then strikes flint and steel against the inside block, and the space within the frame becomes filled with End Portal blocks. Breaking any frame's obsidian or crying obsidian block clears the portal floor automatically.
Roof mode skips the solid floor and is meant for overhead use, where the portal sits above a player who looks up instead of standing on it. Commands switch between the two modes. The mod only affects its own portal blocks: real End Portals, including those in strongholds and the exit portal of the End, keep working as in vanilla. Void Floors only decorates and transports nothing, while the separate Horizontal Portals mod is the one that links dimensions through portals.
The mod is server-side only, so players join without installing it and only the server needs the Fabric file. It is released under the MIT License and is not open source. Files cover 1.21.5 – 1.21.11 with 1.0.1 for 1.21.11 as the latest. Installation needs Fabric Loader and Fabric API.
Key features
Walkable portal floors
Mod-placed portal blocks sit on a solid floor, so stepping onto them does not teleport anyone.
Roof mode for ceilings
A ceiling variant places the portal layer overhead without the floor beneath it, suited to looking up.
Frame-based placement
Activating the interior of an obsidian frame fills the enclosed area and removes the portal when a frame block breaks.
Vanilla portals untouched
Only the mod's own blocks are changed, so real End Portals keep their teleport behavior.

What the author says
Turn any obsidian framed area into a walkable (or overhead) decorative void floor that looks exactly like an End Portal! Without teleporting you anywhere, spawning hostile mobs on it, or requiring anything installed on the client. Vanilla End Portal blocks instantly teleport any entity that touches them to The End…
