# Lost Signal VHS v1.8.1
> **CRITICAL UPDATE:** v1.7 and v1.8 were packaged with Windows-style internal ZIP paths, so Iris could reject them as invalid. **Redownload v1.8.1**, which rebuilds the archive with standard portable paths while preserving every v1.8 shader feature.
Lost Signal VHS is a lightweight post-processing shader pack for Minecraft Java Edition. It keeps vanilla lighting intact while turning the final image into unstable analog found footage recorded and played back through a damaged VHS deck.
## Backrooms & analog horror
Designed for **Backrooms maps, Poolrooms, liminal spaces, horror modpacks, ARGs, machinima, and found-footage videos**. Dedicated **Backrooms**, **Poolrooms**, **Liminal Night**, **Found Footage**, **Rental Tape**, **Broken Signal**, and **Analog Fog** presets recreate fluorescent color, humid haze, unstable exposure, tracking loss, and damaged-camcorder motion while keeping the scene playable.

## v1.8.1 critical packaging hotfix
- Rebuilt the archive with portable paths such as `shaders/composite.fsh`
- Fixed Iris rejecting the v1.7/v1.8 Windows-built archives as invalid
- Added deterministic validation for shader entry points, geometry fallbacks, localization files, unsafe paths, and separators
- Retains every v1.8 Analog Fog feature without shader-code changes
- Live verified on Minecraft 26.2 with Fabric Loader 0.19.3, Iris 1.11.2, Sodium 0.9.1, NVIDIA RTX 5070, and OpenGL
## Analog Fog
- True scene-depth fog enters the signal before YIQ conversion and tape encoding
- Five selectable palettes with density, clear-start, falloff, and world-stable variation controls
- Dedicated Analog Fog preset
- Fog tuning for Backrooms, Poolrooms, and Liminal Night presets
## Authentic signal features
- True NTSC/PAL interlaced field weaving through a persistent history buffer
- Smooth correlated time-base error and feathered tracking tears
- YIQ signal processing, chroma bandwidth loss, phase errors, color killer, and chroma persistence
- Tape generations, VHS SP/LP/SLP/VHS-C/rental formats, oxide wear, RF interference, tape chew, and frame-repeat stalls
- 1980s tube, 1990s VHS, and early-digital camcorder responses with optional REC/battery/timecode HUD
- Performance, Balanced, and Cinematic quality levels
- English and Russian settings menus
## Compatibility
| Minecraft Java | Recommended setup | Status |
| --- | --- | --- |
| 26.2 / 26.1.2 | Iris 1.11.2 + Sodium, OpenGL | Primary |
| 1.21.11 | Iris 1.10.7 + Sodium | Primary |
| 1.21.4 | Iris 1.8.8 + Sodium | Primary |
| 1.21.1 | Iris 1.8.12 + Sodium | Primary |
| 1.20.1 | Iris 1.7.6 + Sodium | Primary |
| 1.21.10 / 1.21.8 / 1.21.5 | Compatible Iris + Sodium | Extended target |
| 1.20.6 / 1.20.4 / 1.19.4 / 1.18.2 | Compatible Iris + Sodium | Extended target |
Extended targets use conservative GLSL 1.20, depth-buffer, and composite interfaces, but have not all been live-tested across every loader, GPU, and driver combination. The pack follows the standard OptiFine shader-pack layout; v1.8.1 was live-verified on Iris.
**Minecraft 26.x requires OpenGL. Do not use the experimental Vulkan backend.**
## Installation
1. Download **Lost Signal VHS v1.8.1**.
2. Place the ZIP directly in Minecraft's `shaderpacks` directory. Do not extract it.
3. Start Minecraft with Iris and OpenGL.
4. Open **Options → Video Settings → Shader Packs**.
5. Select **Lost Signal VHS v1.8.1** and apply it.
6. Open **Shader Pack Settings** to choose a preset and quality level.
No resource pack, external texture, or compute-shader support is required.
