Enable Blur on Books and Signs

Access the Mod Settings

Open your mod configuration menu (usually accessible from the main menu or pause screen, depending on your mod loader). Look for the Blur Perfected section.

Enable Blur for Reading Screens

Locate the option to enable blur effects on additional screens. You should find toggles or checkboxes for:

• Book & Quill screens — when reading or editing books
• Sign editing screens — when placing or editing text on signs
• Command block screens — when writing commands

Enable whichever screens you want to have a blurred background. Each can typically be toggled independently.

Apply and Test

Save your settings and return to your world. Open a book, edit a sign, or interact with a command block. The background should now blur smoothly behind the screen. If the blur doesn't appear, verify the setting is enabled and restart your game if needed.

These settings let you customize your experience — you can blur all screens or only specific ones based on your preference.
