DERCODE - Realistic & Fantasy Path-Tracing Shader

SHADER

A Derivative-based shader recode with path tracing fixes and fantasy effects, but with notable performance trade-offs.

DERCODE is a shader pack built as a thorough recode of the Derivative shader, aimed at players who want a blend of realistic lighting and fantasy-style visual effects. It addresses several bugs found in the original Derivative release and introduces new atmospheric features. The project began as a modification of the Bliss shader in late 2024 but was migrated to Derivative when older Bliss builds could not support the intended feature set. This shader is best suited for users with mid-range to high-end hardware who are willing to accept reduced frame rates in exchange for a distinctive, path-traced look.

The shader’s primary use case is for Minecraft players who want to explore a world with volumetric fog, dynamic shadows, and fantasy-tinted color grading while still retaining the realistic foundation of Derivative. However, be aware that the current implementation of path-tracing functions is not well optimized. Performance can drop significantly on older GPUs or at higher render distances. The developers have stated that the built-in profile system is broken, so users should manually select the High profile for best results. Future updates may rewrite the shader from scratch to improve efficiency.

  • Bug fixes over original Derivative – Resolves several graphical issues present in the base shader.
  • Fantasy effects layered on realistic lighting – Adds custom color palettes, bloom, and glow effects for a dreamlike atmosphere.
  • Path-tracing integration – Provides more accurate light transport but with currently heavy performance cost.
  • Maintained for Minecraft 1.21.11 – Requires Sodium, Iris, and at least 8GB of system RAM.
  • Ongoing development – Project continues to receive updates; changelogs document all recode changes.

To run DERCODE, you need Minecraft 1.21.11 with both Sodium and Iris installed. A GPU with at least 4GB of VRAM is recommended; a laptop GTX 1650 achieved 100–130 FPS at 22 chunks with Full HD resolution and 8GB RAM. Lower-end hardware will likely see single-digit frame rates. Because optimization is currently poor, this shader is not suitable for competitive play or for users who demand stable high FPS. Those who value unique visuals and are willing to experiment will find it a promising project.
