Vitrail: OptiFine/Iris shaderpacks on 26.2's Vulkan renderer (NeoForge + Fabric)
26.2 ships an experimental Vulkan backend, but none of the usual shaderpacks run on it since Iris is still OpenGL. So I wrote a mod that loads them. Same packs, same shaderpacks folder, nothing to convert. The GLSL is translated once at load time into what the Vulkan renderer expects, then it runs as regular pipelines, so there's no runtime overhead from the translation itself.
What works: Complementary, BSL and Bliss are in decent shape and are what I test against. Mellow and Body Camera load. Some packs refuse outright, Reverie for example, because they need things that aren't implemented yet. So don't expect a random pack from your folder to just work, not at this stage.
Distant Horizons works too, mostly. Far terrain goes through the pack like on Iris, water and shadows included. On Fabric the normal DH build is fine. On NeoForge the official build crashes on Vulkan, so I patched it, link below. That part is a bonus, the mod doesn't need DH.
What's missing: voxel lighting (Complementary Ultra), compute shaders, and a bunch of smaller things. It's a beta, it's one person, and the Vulkan backend itself is still experimental, so expect rough edges. If you just want shaders that work, Iris is still the one. This is for people who wanted to try the Vulkan renderer and were annoyed they had to turn their shaders off to do it.
One jar for NeoForge and Fabric. Needs 26.2, Sodium 0.9.x and Chloride (auto-installed with the CurseForge client). LGPL-3.0, source on GitHub.
