Minecraft 1.20.1용 BitNixelet 셰이더

BitNixelet Shader Pack

⚠️ BETA VERSION ⚠️

Hey! This shader is still in development, so there might be bugs and weird stuff. If something breaks - don't panic, that's normal for beta :)

What is this?

Basically, I'm making a shader that turns Minecraft into an old-school pixel game from the 90s. You know, like on old consoles - everything square and with huge pixels? Something like that.

For now only pixelation works, I'll add the rest later

What it does

🎮 Makes everything pixelated

• You can adjust how much to "pixelate" (from 1 to 100)
• I set 32 by default - looks pretty good
• Works simply: takes a bunch of pixels, mixes them into one big one making an 8-bit game analog

🎨 Old colors

• Cuts the palette down to 16 shades per color (like in old games)
• Creates those "steps" between colors
• Just like on ancient computers

✨ Tweaks the picture

• Slightly changes brightness so it's not too dark
• Makes colors 20% brighter
• Generally tries to make it look good

📺 TV Noise (optional)

• Adds old CRT TV static noise effect
• Animated grain that moves over time
• Can be turned on/off in shader settings
• Makes it feel like playing on an old television

How to configure

Main settings

• PIXELATION - how much to pixelate (1-100)
• 1 = almost no pixelation (very fine)
• 100 = strong pixelation (big squares)
• NOISE - TV static effect (0/1)
• 0 = no noise
• 1 = old TV static noise

How it works inside

• Takes the picture and "rounds" pixels into blocks
• Cuts the number of colors to 16 per channel
• Adjusts brightness and saturation so it doesn't look ugly

What it runs on

• Need Iris (won't work without it)
• Minecraft 1.16+ (haven't tested on older versions, might not work), recommend playing on 1.20.1
• Doesn't lag even on weak computers
• OpenGL 2.1 is enough (that's a very old standard)

How to install

• Download and install Iris if you don't have it yet
• Drop the BitNixelet folder into the shaderpacks folder
• In Iris settings select this shader
• Adjust the pixelation setting as you like

What's currently buggy

• Sometimes artifacts appear if you pixelate too much
• Some blocks might look weird
• Interface gets blurry with strong pixelation (don't know how to fix this yet)

Fixed bugs

• Fixed wrong pixelation math that caused weird scaling
• Fixed edge artifacts by preventing texture sampling outside bounds
• Fixed pixel centering for cleaner pixelation blocks
• Fixed potential crashes from division by zero in color calculations
• Fixed color overflow issues with proper clamping
• Fixed inverted pixelation logic (now higher values = more pixelation)
• Fixed NOISE setting not working properly with true/false values
• Optimized luminance calculations for better performance
