Retro PS1 Shader

Retro PS1 Shader

Retro screen effects for vanilla Minecraft 26.3+. No Iris, no OptiFine, no mods. Just a resource pack and the new /posteffect command.

11 ready-made looks: old PS1 horror, clean PS1, CRT TV, VHS tape, N64, Game Boy and Silent Hill fog. Each one is a single command.

How to use

1. Put the pack in your resourcepacks folder and enable it.
2. Turn an effect on: /posteffect add @s rppe:ps1_horror
3. Turn it off: /posteffect remove @s rppe:ps1_horror or remove everything: /posteffect clear @s

Effects

| Name | What it looks like |
|—|—|
| ps1_horror | Low resolution, 15-bit color, dithering, grain, dark foggy corners. The main one |
| ps1_horror_nodither | Same, without the dither pattern |
| ps1_horror_novignette | Same, without the dark corners |
| ps1_lowres | Same, with bigger pixels |
| ps1_crt | PS1 horror on an old CRT TV: scanlines and RGB mask |
| ps1_clean | Just the PS1 look. No horror, normal colors |
| ps1_clean_nodither | Same, without dithering (you get visible color bands) |
| n64_blur | Soft, blurry N64 style |
| vhs | VHS tape: line jitter, color bleed, blur, light noise |
| gameboy | 160×144 in four Game Boy greens |
| silent_fog | Washed out colors and thick white fog around the edges |

The HUD (hotbar, chat, inventory) stays clean. The effects only change the world view.

Tweaking

Every effect has its settings as numbers at the top of its file in assets/rppe/shaders/post/: pixel size, grain, vignette, colors, fog. Edit, save, press F3+T.
