Enum ShadowMatrices 

pub enum ShadowMatrices {
    Single(Mat4),
    Cube(Box<[Mat4; 6]>),
}

View-projection matrices a single shadow-casting light publishes.

Two variants reflect the two atlas binding surfaces consumed by the lit shader: directional / spot use a single matrix sampled against the 2D depth-array atlas, point lights use six matrices sampled against the cubemap atlas.

Cube is significantly larger than Single (6 × Mat4 ≈ 384 B vs Mat4 ≈ 64 B). The variants are boxed to even out memory usage, since most lights are directional / spot and a fat enum would inflate the per-frame HashMap<usize, ShadowMatrices>.

Variants

Single(Mat4)

One view-projection — directional or spot light.

Cube(Box<[Mat4; 6]>)

Six view-projections in [khora_core::math::CubeFace::ALL] order ([+X, -X, +Y, -Y, +Z, -Z]) — point light.
