Polaris Tweaks

Your technical survival companion for Minecraft Java 1.21.1 (Fabric): safety, quality of life and technical tools that improve vanilla survival without cheating. It comes with a searchable menu, configuration profiles and a HUD editor, all with an arctic look.

Polaris Tweaks is closed-source software: this repository only publishes the compiled builds (Releases). The source code is not public. It is based on Polaris Client, with the cheat modules removed.

Philosophy

Polaris Tweaks gives you information, comfort and safety. It does not give you an unfair mechanical advantage:

• No combat modules, no flying, no speed hacks, no X-ray, no ore or chest finders, no fast break or fast place.
• Everything runs on the client and works on vanilla servers. Nothing is installed on the server.
• A few modules can still be against the rules of some servers (Free Camera, Entity ESP, Fullbright, No Fog and Enhanced Placement's block orientation). Free Camera and Entity ESP warn you when you turn them on. Check the rules of your server before using them.

Modules

Building

Module	What it does
Enhanced Placement	Splits the face you aim at into a center square and four border zones. Click the center to place in front of the face as usual, or a border zone to place beside the targeted block. Shows the zone, a grid and a preview of the real block shape and orientation.
Fixed Placement	Stops misplaced blocks when you build fast: it re-checks the face you aim at, skips clicks that cannot place anything, ignores accidental double clicks and discards stray blocks when you place in a straight line.

Block orientation. Pistons, observers, droppers, stairs and similar blocks face where you look. Enhanced Placement can make them face the side where you place them (default) or the face you aim at (hold the orientation key). Your camera never moves: the mod only tells the server the needed look for a fraction of a second while it places the block. Turn off Orient Blocks if a server does not like it.

Technical

Module	What it does
Spawn Rings	Rings with the mob spawning radii around you: 24, 32 and 128 blocks.
Redstone Inspector	Power, delay, mode and direction of the redstone block you look at, signal strength over redstone dust and the blast radius of TNT.
