Bedrock Obfuscator

Hides the bottom bedrock layers in the Overworld so people can't use the pattern against you.

At the very bottom of every Minecraft world there's a layer of bedrock with a random bumpy pattern. That pattern is different in every spot, so people watching your videos or streams can find your coordinates using the server seed and figure out where you are. This mod hides that pattern so they can't.

It only changes what you see client side.

Features

Hides bedrock from Y -64 to -60
Pick any block to show instead (bedrock by default)
Leaves real holes down to the void alone, so it won't cover a gap you could fall through
Won't replace a block you're standing inside, so you never look stuck in the floor
Turn it on and off with a hotkey

How it works

The mod only changes the picture drawn on your screen. The real blocks never change, so mining, walking, falling, and multiplayer all work exactly like normal. Turn the mod off and the real bedrock shows again right away.

Requirements

Minecraft 1.21.11
Fabric Loader
Fabric API
MaLiLib

Controls

Default hotkeys:

Toggle on/off: Left Shift + B
Open settings: U + I

Both can be changed in the mod's settings screen or in Minecraft controls menu.
