Debug

When Iris’ debug mode is enabled, patched shaders are saved to /colorwheel_sources/. The line numbers provided in the error logs correspond to those patched codes.

You may also provide tha Java argument -Dflw.dumpShaderSource=true to your Minecraft instance, instead of enabling Iris debug mode.

Colorwheel provides debug modes to vizualise some data using the /colorwheel debug shader <debug mode>. Currently, you may vizualise:

  • Vertex normals
  • Vertex tangents
  • Vertex tangents handeness (red for -1, blue for 1)
  • Light level
  • Overlay
  • Old lighting
  • Instance ID
  • Model ID
