RGB Block
by VadimCanPlay
RGB Block is a Fabric magic mod that adds a block game where placed blocks create an illusion of walls when viewed from the right angle.
What it does
The mod places a set of colored blocks that players can position to form the look of a wall from a single viewpoint, then step away to see the effect. It is meant for players who want to try a simpler, faster way to build such illusions in creative play. Client and server both need it, so the server and every player install it.
Files are published for Fabric only, for the single game version 1.21.8, with the latest file 1.1.0 dated 2026-03-12. RGB Block is not open source and is released under All rights reserved.
Key features
Wall illusions from blocks
Placing a few blocks in the right arrangement produces the appearance of a full wall when seen from one spot.
Simpler block setup
The block layout needs fewer placements than building the same visual by hand, so the process takes less time.
Creative mode access
The mod is tied to creative mode, and the author notes a planned change in that area in later updates.

What the author says
This mod adds a new block to the game, which is kinda interesting: the RGB Block. For now you can only get it in creative mode, but that will change very soon. You might think: why do we need this block when we can do the same but with maps? Well, it makes the process way more simpler, faster and better and it works…
