A shaderpack that simulates RTX-style ray tracing using screen-space ray marching — the same technique used by SEUS PTGI, Complementary Reimagined, and BSL. True hardware ray tracing isn't accessible from Java Edition shaderpacks (they run on OpenGL, not DXR/Vulkan RT), so this marches rays against the depth buffer each frame to build reflections and a one-bounce GI approximation.
Features
Requirements: OptiFine or Iris (Sodium+Iris also works)
Install: drop the zip into .minecraft/shaderpacks/, select it from Video Settings → Shaders.
