PolyBlur (Motion Blur)

What PolyBlur does PolyBlur adds motion blur to Minecraft. It gives you three different blur methods and a strength slider so you can tune the effect to taste. The mod is a fork of MonkeyBlur that migrated from ASM to Mixin, moved its configuration to OneConfig, and fixed several rendering bugs along the way. ## Blur types you can choose Monkey Blur uses an approach based on BSL and NVIDIA blur shaders. Phosphor Blur adapts Minecraft's built-in phosphor shader and behaves similarly to the blur found in Lunar Client and BLC; it's the default. Moulberry Blur reaches a comparable look through a different technique originally created by Moulberry. You pick one in the config. ## Strength control A dedicated strength setting lets you dial the intensity up or down. This was added in the fork and is not present in the original MonkeyBlur. ## OptiFine interaction The config includes an option to forcefully disable OptiFine's Fast Render when the blur is active. This helps avoid conflicts between the two rendering pipelines. ## Compatibility and requirements PolyBlur runs on Fabric only. The client side is required; the server side is unsupported. Supported Minecraft versions are 26.3, 26.2, 26.1.2, 26.1.1, 26.1, 1.21.11, 1.21.10, 1.21.9, 1.21.8, 1.21.7, 1.21.5, and 1.21.4. The project is licensed under GPL-3.0 with a Minecraft linking exception. ## Known fixes in the fork The repository notes fixes for the shader not applying blur, the shader not applying blue, framebuffer updates when resolution changes, and a blur reset on perspective change. A recent release also addresses compatibility with NEU negative cape.
