Vanilla Raytracing For Java! (support 3d Models) May 2026

The support for volumetric fog and light shafts (god rays) significantly enhances the "mood" of vanilla Minecraft.

Often includes extensive menus to tweak bounce counts, denoising strength, and resolution scaling. Cons: Vanilla Raytracing for Java! (Support 3D Models)

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: The support for volumetric fog and light shafts

Requires Iris Shaders (recommended for performance) or Optifine . Rain creates puddles with accurate reflections, and metals

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].

Requires Iris Shaders or Optifine . It may conflict with other "core shaders" that modify the same rendering pipelines. Setup and Requirements
