Enum ShadowUpdate 

pub enum ShadowUpdate {
    EveryFrame,
    Hybrid,
}

How often each cascaded-shadow-map slice is re-rendered. The shadow pass re-rasterizes all scene geometry into every cascade, so it is one of the heavier passes; updating distant cascades less often cuts that cost.

hybrid (the default) re-renders the nearest cascade every frame (so close shadows stay crisp) and rotates through the farther cascades one per frame. Distant shadows then lag a few frames while the camera moves, which is imperceptible at that range. every_frame re-renders all cascades every frame: pick it for scenes with fast-moving shadow casters where even distant shadow lag is unacceptable. Each cascade is always primed (rendered once) before it is sampled, so there is never missing shadow data.

Variants

EveryFrame

Re-render every cascade every frame.

Hybrid

Re-render the near cascades every frame and the distant ones on a rotation.
