Blur

Blur is a mod that adds a blur shader to the background when the player has a GUI open such as their inventory or a crafting table. There are a few settings the player can configure to change the blur this mod applies. These can be found in Blur's config options in the "Mod Options" menu.

Settings

 * Fade Time - The amount of time it takes in milliseconds for the background to transition to a full blur when a GUI is opened.
 * Gradient Start Color - an ARGB Hexadecimal value representing the color the blur will be. This value controls the color starting from the bottom of the screen.
 * Gradient End Color - an ARGB Hexadecimal value representing the color the blur will be. This value controls the color from the top of the screen.
 * By default the gradient start and end colors are black with 45% transparency with ARGB Hex value: 75000000
 * Since the colors are applied with a gradient, the background will blend between the two colors in the middle of the screen.
 * GUI Exclusions - A list of classes that the blur shader will not effect. By default only contains the chat GUI. These can be used to prevent the blur in certain GUIs.
 * Radius - The intensity of the blur shader. Reducing this value will increase performance, while decreasing the blur.

Note
It is notable that if Optifine's "Fast Render" setting is turned on, it will disable this mod's blur shader, preventing it from applying the blur.
