About this Mod

Void Block

Simply adds a block that renders the void portal effect. Works for Fabric 1.21.1 and works with or without shaders! I will almost certainly never, ever be updating or changing this mod, because I'm genuinely surprised it works at all as it is, and I'm terrified that if I change ANYTHING inside it it'll break.

Required on both server and client. No dependencies.

Features

  • Void Block - renders the End Gateway effect

  • Shader compatibility - NOTE: I recommend Solas Shader as it's one of the few I've come across that renders the End Portal effect screen-space aligned. Others don't, and so you can see the 'seams' where perpendicular surfaces built of void blocks meet. MASSIVE thanks to fayer3 for adding the shader support :)

  • Redstone controllable
    Redstone control can be toggled on or off in the configs by setting

    "enableRedstoneControl": <true|false>

Credits

This mod started as a 1.21.1 port of LuminaSapphira's Block of Sky, which itself was a port of Literal Sky Block and used code from the Fabric port of that mod, Literal Sky Block Fabric. All of these projects are licensed under LGPL-3.0.

Shader support was very kindly added by fayer3 - MASSIVE thanks to them

Frequently Asked Questions

Void Block server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.1). You can switch loaders with one click in the panel.

Is Void Block compatible with fabric?

Void Block officially supports fabric for Minecraft 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Void Block – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Void Block consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
