Why make Neutron?
I was sitting in my high school cafeteria when I read online how nuclear fusion has been '30 years away' for nearly 50 years now. Thinking back to the fusion reactors I constructed in Voltz, it made me bitter to think that I'd likely never receive electricity generated from a fusion power plant in my lifetime.
Though that may still be the case, the news that the Lawrence Livermore National Laboratory had achieved ignition on December 5th, 2022 had me running around my house shouting with excitement. To celebrate the occasion, I vowed to create a modpack to recapture the discovery I once had playing Voltz for other red matter veterans and new scientifically inquisitive players.
Why start development now?
Neutron has been in development behind the scenes for quite some time. It started as a project for my close friends but shifted towards being a spiritual successor to Voltz as time went on. As with most creators on these platforms, life got in the way too (college education, home–buying and renovating, career–path changes, etc).
I have recently found more time to develop Neutron and I will continue to work toward an official release. Custom mods are planned to be added in the future as well. I'm looking forward to providing others with an explosive multiplayer modded Minecraft experience!
ARR?
I have not spent time reading other licenses, but I understand it is always easier/recommended to restrict access and grant it down the line rather than vice versa. As is, Neutron is NOT a finished product, but I hereby grant others the ability to download the modpack to play and record; mentioning myself, TheAutomaton, is always a plus! Further declarations and specifics will come in time.

Frequently Asked Questions
Neutron server crashes or won't start – what to do?
Most common causes: insufficient RAM or wrong neoforge loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.
How much RAM does a Neutron server really need?
Minimum 6 GB, recommended 8 GB for stable performance. per 5 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €12/month).
Can I add custom mods to Neutron without conflicts?
Yes, but check compatibility: only use mods for the same loader (neoforge) and same Minecraft version (1.20.1). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
Neutron server lagging – performance tips
1) Increase RAM to 8 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
