It utilizes Physically Based Rendering (PBR) , meaning surfaces have properties like roughness, metalness, and emission. Rain creates puddles with accurate reflections, and metals exhibit a distinct luster [2, 4]. Pros and Cons Pros:
Offers a visual overhaul comparable to high-end shaders like SEUS PTGI or Continuum RT. Vanilla Raytracing for Java! (Support 3D Models)
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]. It utilizes Physically Based Rendering (PBR) , meaning
Requires Iris Shaders or Optifine . It may conflict with other "core shaders" that modify the same rendering pipelines. Setup and Requirements It utilizes Physically Based Rendering (PBR)
You must use a compatible PBR Resource Pack (like LabPBR) to see the full "raytraced" effect on textures.
