Solar Neutron Activator Tweaks enhances SNA (Solar Neutron Activator) by allowing it to work without requiring sunlight or clear line of sight to the sky. It is a simple tweak to streamline production in modpacks or worlds where sunlight is innaccesible.
Key features include:
1. Always-on production: Your SNA will always work in any conditions (so long as pipes and in/out ports are configured as per Mekanism's standards) independantly of wether it has sunlight or a block over it.
2. Dimension-independant: The machine will operate even in other dimensions, for example: the Nether, End, compact machine frames, Mining dimension.
3. Config menu: A config menu for Enabling or Disabling the Always-on-production function, or setting a custom production rate multiplier.
4. Compatability: It works within the range of the newest and some older versions of Neoforge, and should work with any neoforge Mekanism for 1.21.1. You are welcome to try on other versions, since it might still work as long as its Neoforge. No garuantees tho
This tweak is ideal for players whose bases are underground, located in dimensions with limited/no sunlight, or who simply want uninterrupted Polonium/Tritium production. It keeps your setup efficient and prevents downtime during night or low-light areas. Removes the need to set up massive reserves to survive night time.
The mod works with singleplayer worlds and hosted worlds using the Essentials mod.
