📼 OldNightmares Shader

"Some memories are better left forgotten."

OldNightmares transforms Minecraft into a VHS experience - whether you're going for a deep horror atmosphere or just that warm, nostalgic glow of an old tape, this shader adapts to your vision.

Effects

• VHS Scanlines - authentic horizontal scan lines for that old-tape feel.
• Film Grain & Noise - dynamic noise that makes every frame feel recorded.
• Chromatic Aberration - color fringing on the edges of the screen.
• Horror Vignette - deep black borders that close in around you.
• Blood Vignette - pulsing red vignette.
• VHS Glitch - random tape glitches that break the image.
• Barrel Distortion - wide-angle lens distortion.
• Screen Warp - subtle warping that makes the world feel unstable.
• Horror Color Grade - desaturated, green-tinted atmosphere.
• Motion Blur - smooth, cinematic movement blur.

Fully Customizable

Every single effect can be toggled on/off and tuned with sliders directly from the OptiFine shader menu. Crank everything up for a terrifying found-footage experience, or dial it back for a subtle nostalgic VHS look. The choice is yours.
