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].
Requires Iris Shaders (recommended for performance) or Optifine . Vanilla Raytracing for Java! (Support 3D Models)
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]. Unlike standard shaders that use "faked" shadows, this
