About this project
What does Environmental Tech Legacy add?
Environmental Tech Legacy is the classic Environmental Tech: a vast selection of very powerful multiblock machines, kept going as its own mod. It's separate from Environmental Tech, and the two can be installed together.
On Minecraft 1.15.2 and earlier this is the mod on the Environmental Tech page. This page has its releases from 1.16.5 on.
Features
- Void Miners: mine ores, resources and plants from the void.
- Solar Arrays: generate large amounts of energy from the sun.
- Lightning Rods: generate large amounts of energy from lightning.
- Nanobot Beacons: give yourself or others effects, personally or over a range.
Each machine comes in six tiers, and an in-game guide covers how to build and use them.
Coming from 1.15.2
Your worlds carry across: blocks, items and machines keep working, and formed multiblocks stay formed. Your settings don't, as config/environmentaltech isn't read, so they go back to their defaults.
Requirements
- ValkyrieLib
- Install it on both the client and the server.
Can I use this in my modpack?
CurseForge, Modrinth and FTB modpacks: go ahead. Packs on external sites: get my permission first, and link back to this project page.
