Lumen Java 1.0.0-beta.2 - Iris shader fix
Pre-release
Fixes Xray ore and chest outlines disappearing behind terrain when an Iris shader pack is enabled on Minecraft Java 26.3.
Through-wall outlines now render after shader composition, using the current world camera projection. Zoom, filters and the Insert menu remain available. Turning through-wall rendering off still hides occluded outlines.
Tested in separate development instances with and without Iris. The shader run used Iris 1.11.6, Sodium 0.9.3-alpha.1 and Complementary Reimagined r5.9.3, including switching shaders off/on during play. Ten unit tests and the client game tests passed; captured image pixels verify that all four test ore/chest outlines are visible through the wall. Shader lighting may ignore Fullbright. Other shader packs and complete modpacks need separate testing.
Update in Prism Launcher: close Minecraft, open the instance folder, remove the previous Lumen Java JAR from minecraft/mods, and put lumen-java-1.0.0-beta.2.jar there. Keep Fabric API installed. Existing Lumen settings are retained.
Requires Minecraft 26.3, Java 25, Fabric Loader 0.19.5+, and Fabric API 0.161.0+26.3. Iris is optional. Client only; no EXE, DLL or in-game updater.
