Changes
Lost Signal VHS v1.8.1 — Critical Packaging Hotfix
- Fixed the release ZIP so Iris can discover the required
shaders/directory. - Replaced Windows-style backslash entry names with standard portable ZIP paths.
- Added automated validation for shader entry points, geometry fallback programs, localization files, unsafe paths, and invalid separators.
- Retains every v1.8 Analog Fog feature and compatibility target without shader-code changes.
- Live verified on Minecraft 26.2 with Iris 1.11.2, Sodium 0.9.1, NVIDIA RTX 5070, and OpenGL.
Important: v1.7 and v1.8 were packaged incorrectly and may be rejected as invalid by Iris. Please update to v1.8.1.
Primary targets: 1.20.1, 1.21.1, 1.21.4, 1.21.11, 26.1.2, 26.2.
Extended compatibility targets: 1.18.2, 1.19.4, 1.20.4, 1.20.6, 1.21.5, 1.21.8, 1.21.10. These are compatibility targets and have not all been live-tested across every loader/GPU/driver combination.
Minecraft 26.x requires Iris with OpenGL; do not use the experimental Vulkan backend.
