1.12.2 Mod Compatibility

None of the mods below are required. The lists describe how each interacts
with CrankShaft when both are installed. Any mod not listed here can be
assumed compatible — please file an issue if you find otherwise.

Patched

CrankShaft has explicit compat code for these.

  • Renderers: Sodium ports (Neonium, Vintagium, Relictium, Celeritas),
    Nothirium (with RenderLib).
  • Lighting engine: Alfheim, Cubic Chunks.
  • Smart animated textures: LoliASM (aka CensoredASM).
  • Dynamic lights: Celeritas Dynamic Lights, OptiFine's Dynamic Lights.
  • Uniforms: AquaAcrobatics (swimming), Wings (flying), Fluidlogged-API
    (fluidlogged blocks) are recognized by CrankShaft's uniform writers.

CrankShaft fixes Celeritas Dynamic Lights' entity lighting on Neonium, Vintagium, and
Relictium.

Partially compatible

Some of their features do not extend to Flywheel-instanced visuals.

  • OptiFine — shaderpacks are not supported.

Incompatible

Both mods will load and run, but their interaction is broken on Flywheel-instanced
visuals.

  • Albedo (elucent) and ColoredLux (zeith / dragon-forge) — they bind
    their own GL programs for the world and entity render passes.
