About this Mod
Replaced with better toggable alternative directly in Polymer library!
Enchantment Table fix was already unnesesary with 1.21.1.
With latest Polymer version for 1.21.4, the fix for Stonecutters is now bundled and can be enabled in config, allowing to use it's vanilla ui while having all the modded recipes correcly (instead of replacing the ui entirely).
Server UI Fix
This mod allows you to replace Stonecutter's and Enchanting Table's interface with Chest UI replica.
This solves an issues where:
- Stonecutter shows incorrect recipes, as it checks for them based on client side item type
(which can be incorrect for modded items). - Enchanting Table doesn't show modded predicted enchantment names.
It is designed to be used on content-modded servers, that allow vanilla clients to join, for example if they use
Polymer-based mods or PolyMc.
By default, mod is disabled and requires you to enable specific replacement in config file: config/serveruifix.json.
