Troubleshoot Glass GUI Not Appearing
Verify Mod Installation
Confirm that ReGlass Mod is properly installed in your mods folder and that your mod loader (Forge, Fabric, etc.) recognizes it. Check your launcher's mod list to ensure ReGlass is enabled and has no conflict warnings.
Check for Conflicting Mods
Other UI or GUI-modifying mods may conflict with ReGlass, preventing the glass aesthetic from loading. Temporarily disable recently added mods and test whether glass GUIs reappear. If they do, you've identified a conflict.
Clear Cache and Restart
Minecraft caches shader and texture data. Delete your shader cache or resource pack cache folder, then fully restart the game. This forces Minecraft to reload ReGlass's visual assets.
Verify Configuration Files
If ReGlass has config files, ensure they haven't been corrupted or set to disable the mod's features. Reset the config to defaults if needed by deleting the config file and restarting—the mod will regenerate it.
Test with Vanilla Screens
Open a standard chest, crafting table, or your inventory. If glass styling appears there but not elsewhere, the issue is likely mod incompatibility rather than a ReGlass installation problem.
