Requires Iris Shaders (recommended for performance) or Optifine .
One of its standout features is the ability to handle complex 3D geometry . While many older ray-tracing packs struggled with non-blocky shapes, this version correctly calculates light hits on custom 3D models (like detailed furniture or vegetation) rather than treating them as flat planes [2, 4]. Vanilla Raytracing for Java! (Support 3D Models)
You must use a compatible PBR Resource Pack (like LabPBR) to see the full "raytraced" effect on textures. You must use a compatible PBR Resource Pack
Often includes extensive menus to tweak bounce counts, denoising strength, and resolution scaling. Cons: It produces realistic soft shadows, ambient occlusion, and
Unlike standard shaders that use "faked" shadows, this project calculates light bounces across surfaces. It produces realistic soft shadows, ambient occlusion, and colored lighting from glowing blocks [2].
Despite the "Vanilla" name, it is extremely demanding. You generally need a modern dedicated GPU (Nvidia RTX 20-series or AMD RX 6000-series and above) to maintain 60 FPS [1, 2].
