Smooth Join
Eliminates lag spikes when joining a world by dynamically adjusting render distance.
Quick answer
Which Smooth Join release should I use?
Smooth Join 1.3.1 targets 26.2 with Fabric. It must be installed on the client. Do not install it on the dedicated server. All 1 required mods have matching files.
Where it goes
Is Smooth Join required on the client, server, or both?
It must be installed on the client. Do not install it on the dedicated server.
This file is marked client-only.
What else does Smooth Join 1.3.1 need?
1.3.1. Change the file and its required mods may change too.
Install Fabric API first. We found matching files for this game-version and loader setup. 1 comes through another mod in the chain.
1 extra mod was pulled in by another dependency. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

Description
❓ The Problem
Does your game freeze or lag heavily when you join a server or load a single-player world?
This happens because Minecraft tries to load and render all chunks around you at once. For lower-end PCs or heavy modpacks, this causes a massive CPU spike, freezing your screen for seconds.
✅ The Solution
SmoothJoin solves this by temporarily lowering your render distance to the minimum (2 chunks) before the world finishes loading. Once you are safely in the game, it waits for a few seconds and then progressively restores your render distance to your original setting.
✨ Features
- Smart Init: Detects the connection start and lowers load immediately.
- Lag-Free Entry: Drastically reduces the "Building Terrain" load time.
- Progressive Restoration: Slowly increases view distance (e.g., 1 -> 2 -> 3 -> 4) to prevent secondary lag spikes.
- Safety Lock: Automatically restores your settings if you disconnect or crash during the process.
- Client-Side Only: You don't need to install this on the server.
⚙️ How it works
- Connect: You join a server. Mod sets render distance to 2.
- Wait: Game loads quickly. Mod waits for ~20 seconds (buffer time).
- Restore: Mod increases render distance by 1 chunk every second.
- Done: You enjoy a smooth view without freezing!
Incompatible with Concurrent Chunk Management Engine
