Cambium

About this project
What does Cambium add?
A Reimagined Solarpunk Experience.
Cambium departs from the traditional "high-tech" resource mods to explore a world where industry and ecology are one and the same. It introduces a closed-loop resource system that rewards patience, biological management, and solar efficiency.
The Core Cycle
Solar Digestion: Utilize the power of the sun to break down organic matter. The Solar Digester is the heart of your operation, converting waste into the chemical precursors needed for advanced growth.
Synthetic Flora: Cultivate Resource Trees. These aren't simple ore-bushes; they are complex organisms that metabolize sunlight and minerals into Iron, Gold, Diamond, and Emerald.
Regenerative Soil: Automation is earned, not given. Use the byproducts of digestion to create Mineral Soil, the only medium capable of supporting high-yield resource trees.
Features
Integration: Start of JEI support for easy recipe discovery.
Organic Automation: A unique logistics loop that prioritizes biological growth over traditional pipes and wires.
Mod Support: Easy ability for supporting modded resources in future updates! (Vanilla resources for now)
Modern Fabric: Built for Minecraft 1.21.11 on the Fabric loader
Disclaimer!
Cambium is a hobby mod. More proof of concept. I want to build towards a eco-styled tech solarpunk mod that rivals current tech mods. This is still in early development so, features, changes, tweaks, bug-fixing, will all happen over time. See more of the roadmap over on GitHub!
