适用于 Minecraft 1.20.1, 1.21.1 的 NostaLens 光影

NostaLens

A custom shader pack for Minecraft. This pack requires OptiFine or Iris Shaders to work.

Features

• Fisheye Lens Effect
• A wide-angle lens effect that distorts towards the edges of the screen. Player arms and held items remain undistorted for playability.
• Nostalgic Color Grading
• Slightly increased vibrance with a warm, faded, nostalgic tone.
• Subtle Analog/VHS Noise
• Chromatic Aberration: Recreates the optical phenomenon where red and blue colors shift at the edges of the screen.
• Scanlines: Faint horizontal lines resembling old CRT monitors.
• Tracking Noise & Film Grain: Extremely subtle screen jitter and fine film grain that do not interfere with gameplay.
• Soft Shadows
• Features cool-toned ambient shadows and smooth PCF soft shadows.

Installation

• Install OptiFine or Iris Shaders for Minecraft.
• Place the downloaded ZIP file (do not extract it) into your Minecraft shaderpacks folder.
• Example: %appdata%\.minecraft\shaderpacks
• Go to Video Settings > Shaders in-game, select this shader pack, and apply it.

Customization

You can tweak the settings by opening shaders/final.fsh in a text editor. Modify the following values at the top of the file:

• STRENGTH = 0.2; // Fisheye intensity (higher values increase distortion)
• VIGNETTE = 0.4; // Vignette darkness (higher values make corners darker)
