About this Mod

YouMatter is a Minecraft Forge mod.
You know that fluid called "UU-Matter" from IndustrialCraft2, don't you? Well, here you have it as a standalone mod.
I added some quirks that make it slightly less overpowered, such as adding an extra requirement for producing U-Matter.
Why?
IC² is outdated, has many bugs and often is just included in modpacks because of its UU-Matter features. That was the inspiration for creating a standalone mod.
How to use
- Create some U-Matter with a U-Matter Creator, some stabilizer and a lot of power.
- Scan your desired item in the Scanner
Note: Make sure that there is an Encoder next to the scanner! Also, the scanner will consume your item after scanning. - Put a thumb drive with enough empty space in the encoder and wait
- Transfer your generated U-Matter to the Replicator
- Put your thumbdrive in the replicator, select your mode (single run or multiple runs) and activate the machine!
- There you go!
FAQ
Q: How can I get the Portable Black Hole needed for the Creator?
A: You can find portable black holes in every chest in end mansions (only in 1.12.2, newer versions have a crafting recipe. By the way, you can just put a black hole in a crafting table and duplicate it!)
Config
YouMatter's Config allows you to set a default required U-Matter amount for the duplication of items and set overrides for special items (e.g. set the required amount for stone lower than default or set it higher than default for diamonds)
In order to set the default amount, use the option uMatterPerItem and enter the amount in milibuckets. You can copy the format of the default overrides and change the name of the item and the amount on your own.
As of version 1.3, you can create a Black- or Whitelist. You have the option to add items to a list called specialItems. Using the option useAsBlacklist you can decide whether to allow or disallow the Items in specialItems to be duplicated.

YouMatter server crashes on startup – what to do?
Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.19.4). You can switch loaders with one click in the panel.

Server lagging with YouMatter – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if YouMatter consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
