AutoCape

Does your cape look great with armor but completely ruin your skin without it? This mod solves that problem by dynamically managing cape rendering based on your equipped chest gear.

It automatically shows your cape the moment you equip a chestplate or elytra, and hides it when you take them off, keeping your skin looking exactly as you intended.

Includes 3 modes: Global (renders all players), Local (renders only you), Off (vanilla)
You can easily switch between them with ModMenu

This is a client-side mod so you can play on the servers with no worries.
