TetraModify Core Mod FAQ
10 questions players actually ask, answered.
Do I need to install TetraModify Core Mod separately or does it come with Tetra addons?
TetraModify Core Mod is a library mod that must be installed separately in your mods folder. Many Tetra addons depend on it, so check your addon's requirements—if it lists TetraModify Core as a dependency, you'll need to download and install it alongside Tetra itself.
What does 'embeds MixinExtras' mean and why should I care?
MixinExtras is a tool that prevents different mods from conflicting when they modify the same game code. By embedding it, TetraModify Core Mod reduces crashes that happen when you run multiple mods that tweak Tetra or custom equipment together.
I'm getting crashes when using multiple Tetra addons together. Is TetraModify Core the fix?
Possibly—if your crash log mentions mixin conflicts or IModularItem errors, TetraModify Core Mod should help stabilize things. Make sure it's installed and that all your addons are compatible with the same Tetra version.
Can I use TetraModify Core Mod without any Tetra addons?
TetraModify Core Mod is designed as a library for addon developers and addon users, so it won't add content by itself. You need Tetra and at least one addon that depends on TetraModify Core to see any gameplay changes.
What are IModularItem wrappers and when would I need them?
IModularItem wrappers are code tools that let addon creators safely interact with Tetra's custom tool system. If you're developing a mod that adds custom equipment or modifies tools, these wrappers make your code more stable and compatible.
My custom tools aren't appearing or working. Could TetraModify Core be the problem?
Check that TetraModify Core Mod is installed first, then verify your addon is up to date and compatible with your Tetra version. If the addon uses IModularItem wrappers correctly, TetraModify Core should help it work—if not, the issue is likely in the addon itself.
Does TetraModify Core Mod affect performance or add lag?
TetraModify Core Mod is a lightweight library that actually improves stability by reducing mixin conflicts. It shouldn't cause lag; in fact, preventing crashes from mod conflicts can make your game run more smoothly overall.
Can I run Tetra addons without installing TetraModify Core Mod?
Some older or simpler addons may work without it, but most modern Tetra addons list it as a required dependency. Always check your addon's description or README to see if TetraModify Core Mod is needed.
I see mixin errors in my log. How do I know if TetraModify Core Mod is installed correctly?
Check your mods folder to confirm the TetraModify Core Mod jar file is there alongside Tetra. If it is and you're still seeing mixin errors, try removing other mods one at a time to isolate the conflict, or check addon compatibility with your Tetra version.
Is TetraModify Core Mod required for single-player or only multiplayer servers?
TetraModify Core Mod is required in both single-player and multiplayer if you're using addons that depend on it. The library prevents conflicts regardless of game mode, so install it the same way for both.
