Aeronautics: ModernUI Compat
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
External compatibility patch for Create Simulated/Aeronautics creative-tab section banners and Modern UI tooltips.
⬇ Download on ModrinthWhat it fixes
Create Simulated 1.3.1 draws SimulatedCreativeTab.renderBanners(...) from a CreativeModeInventoryScreen.render@TAIL mixin. That places the custom section banner after the vanilla tooltip pass. Modern UI's translucent tooltip background/shadow therefore blends against the vanilla empty creative slots first, and Simulated paints the banner over that result afterwards.
