Erya Tech (Mobile Factory Extension)
The Erya Tech is a technology that add many if not all vanilla Structures to the game, but with an easy way to build them.
In addition, Erya Structures use Environmental heat to work (Instead of Energy), but this make them a little less efficient than vanilla ones.
Erya Temperature Logic
The Erya Extension introduce a new Temperature system where every Chunks have it's own temperature. The Chunk Temperature equalize with its neighbor Chunks.
If the temperature is below 0°C, snow will appear and water will start to freeze.
If the temperature is above 0°C, snow and water will begin to melt.
