About this project

What does Substrate add?

the word Substrate textured with the top texture of Deepslate, a dark grey stone

Sodium has updated and removed the point that this mod hooked into. Given that my interest in maintaining this mod was already low and I was planning on archiving it when Minecraft switched to Vulkan anyway, I've decided to stop work on it now. Thanks for all the support! Anyone who wants to try and make the mod work is free to fork it :)

This mod is a fork of Bedrodium by kirillirik.

The word

Requires Sodium (or Embeddium^).

Small optimization by removing the invisible sides of the bottom/ top layer of the world. For the player, these sides are visible only when necessary. (The bottom layer of polygons in the Overworld will be deleted, and the bottom and top layers in the Nether). While the mod is themed around Bedrock, the mod makes no actual checks for block type and can provide a benefit even on floating island worlds (such as mini game servers!)

^Only on NeoForge 1.20.x, or the Special Embeddium build for 1.21.1
