1.8.13 ​

Swofty Launcher for F1 25 1.8.13 lets shader effects give their own textures mip chains: smaller copies of the texture, each half the size of the one before, that a pass can sample at any level. Effects use them to average a whole picture in one read, for exposure and sky metering, and for cheap blurs.

  • An effect texture can declare "mips": N, the number of levels including the full-size one, up to 12. After every pass that writes the texture, the launcher rebuilds the smaller levels from it, in game and in the Preview.

    "textures": [
  { "name": "stats", "width": 64, "height": 32, "format": "rg16f", "mips": 7 }
]

  • Passes read a level with input_lod(i, uv, lod) (filtered within and between levels), input_lod_point(i, uv, lod) (the nearest texel), and its size with input_size_lod(i, lod). input(i, uv) keeps reading the full-size level. See Shader configs and effects.
