Blur+ Guide: Fade Times, Animation Curves, and Title Screen Blur

guide

Blur+ controls how the game's menu blur appears, disappears, and which screens it affects. Everything is handled through the mod's own settings interface and its hotkeys rather than through crafting, so you configure it by opening that interface and adjusting the options described below.

Choosing Which Screens Get Blurred

Several toggles decide where the blur effect is allowed to appear. Each one is a simple on/off switch:

blurContainers controls blur behind container interfaces.
blurBooks controls blur behind book screens.
blurCommandBlocks controls blur behind command block screens.
blurDeathScreen controls blur behind the death screen.
blurSigns controls blur behind sign editing screens.
blurTitleScreen controls blur behind the title screen.

Turn a toggle on to let that screen blur, or off to leave it clear.

Reducing Blur and Darkening the Title Screen

Two options adjust the overall look rather than individual screens:

reduceInGameBlur lowers the amount of blur applied to in-game screens.
darkenTitleScreen darkens the title screen background.

Use reduceInGameBlur when the blur feels too heavy during play, and darkenTitleScreen when you want the main menu backdrop to sit darker behind the interface.

Fade In and Fade Out Timing

Two numeric fields set how long the blur takes to appear and to vanish:

fadeTimeMillis — the fade-in duration, measured in milliseconds.
fadeOutTimeMillis — the fade-out duration, measured in milliseconds.

Enter a value in each field to speed up or slow down the transition. Larger numbers mean a longer, softer transition; smaller numbers mean a quicker one. The two are separate, so the blur can fade in at a different pace than it fades out.

Animation Curves

The shape of the transition is set by two curve options:

blurAnimationCurve — the curve used for the blur animation.
backgroundAnimationCurve — the curve used for the background gradient animation.

Pick a curve for each to change how the transition accelerates and settles over its fade time.

Gradient Background Options

If you prefer a gradient behind menus instead of a flat backdrop, these settings build it:

useGradient — enables the gradient as the background.
gradientStart — the starting color of the gradient.
gradientEnd — the ending color of the gradient.
gradientStartAlpha — the transparency of the starting color.
gradientEndAlpha — the transparency of the ending color.

Set useGradient on, then choose both colors and both alpha values to control how opaque each end of the gradient is.

Screen ID Lists and Vanilla Blur Overrides

Blur+ can be told which screens to skip and which to treat specially. Three list fields handle this:

forceEnabledScreens — screens where the vanilla blur effect is forced on.
forceDisabledScreens — screens where the vanilla blur effect is forced off.
A third list field holds screens that Blur+ itself should not animate.

To find the identifier for a screen you want to add, use the on-screen display option. When active, it shows the current screen's ID in the top-left corner of the game window. Read the ID there, then add it to the appropriate list field.

One option mirrors the Menu Background Blur setting found in Minecraft's Accessibility Settings, so the two stay in step with each other.

Working With Hotkeys

Where an action has a hotkey, the specific key is not fixed by the mod. Open the controls menu and assign the corresponding hotkey yourself, then use it whenever you want to trigger that action in game.
