PackSettings

Remarks

⚠ Resolution is required because Margin is counted in texels. docs/plan/42 § D8. A margin expressed as a fraction of UV space is a bug with a two-year fuse: it looks right at the resolution it was tuned at, and the same asset at half resolution bleeds across islands at mip 3, in a build nobody associates with the packing change. Bleeding is then misdiagnosed as a sampler problem roughly always.

⚠ Spacing is distributed evenly across every chart rather than applied per island as it is placed. That is the visibly better behaviour even when nothing bleeds — uneven gaps read as carelessness in an atlas — and it is the one thing a standalone packer is bought for.

Fields and properties (7)

• public required int Resolution

  The atlas's edge length in texels. Required, and the reason is Margin.

• public int Margin

  How many texels of empty space separate two islands.

• public PackQuality Quality

  How hard to try.

• public PackOverflow Overflow

  What to do when it does not fit.

• public int Rotations

  How many orientations an island may be tried in, as quarter turns. One means none.

• public float TexelDensity

  Texels per world unit every island is scaled to, or zero to keep each island's own scale.

• public int CoreLimit

  How many islands the expensive core will place before the cheap tail takes over.
