Changes

v5.0a

Fixed

  • Sky colour space: the atmosphere scattering LUT is now decoded from Rec.2020 into the pack's working colour space before it is used, instead of being read as if it were already in the display gamut. Previously the sky picked up a shift in hue and saturation (and could wash out / look wrongly tinted) because Rec.2020 primaries were interpreted as sRGB.
  • The conversion uses the pack's row-vector convention (v * M), so the matrix order in color.glsl is rec2020ToWorkingColor (rec2020ToXyz * xyzToWorkingColor).

Technical

  • Added rec2020ToXyz, xyzToWorkingColor and the rec2020ToWorkingColor macro in shaders/lib/util/color.glsl.
  • Applied the conversion at all six scattering-LUT sample sites in shaders/lib/atmos/air/atmosphere.glsl (single-scatter + multi-scatter rays, both the in-scatter and the transmittance/ambient paths).
