StellarCore Project

This mod requires MixinBooter 8.0+ and ConfigAnyTime 2.0+ to work!

Introduction

StellarCore is a mod that provides extensive bug fixes, performance improvements, and additional features across a wide range of mods, driven by Mixin technology.

Both Server and Client need to install this mod.

There are too many features to list on this page, look for features on the Sample Configuration page!

Compatibility Note

StellarCore is designed to work with other mods, but as a result there are parts that do not work with some mods, the following are parts that may need to be manually configured by the user:

CensoredASM

  • resourceLocationCanonicalization must be turned to false to use StellarCore's ResourceLocationCanonicalisation feature

VintageFix

  • vintagefix.mixin.dynamic_resources must be turned to false to use StellarCore's ParallelModelLoader feature
  • vintagefix.mixin.dynamic_resources must be turned to false to use StellarCore's StitcherCache feature
  • vintagefix.mixin.textures must be turned to false to use StellarCore's ParallelTextureLoad feature
  • vintagefix.mixin.resourcepacks must be turned to false to use StellarCore's ResourceExistStateCache feature

How is it different from xxx?

We have more (currently 100+ features, adjustable in the config file).

Like most fix mods, we modify the code to make features work, but our invasiveness is minimal, so you can usually install it alongside other mods without issues.

Why do most config files lack detailed descriptions?

This mod is still in a relatively early stage of development, but they are already stable!

Can I add this mod to my ModPack...?

Yes! You can freely add this mod to your ModPack and modify it without restrictions, as long as you are not a bad actor.

I encountered xxx issue...
