pub const FOG_FROXEL_X: u32 = 80;Expand description
X/Y/Z dimensions of the volumetric-fog froxel volume. Sized to keep the
per-frame compute cost modest (~230 k threads per dispatch) while
preserving enough screen-space detail for shaft-of-light shadowing.
Backends that implement the froxel path read these constants directly;
the values also ride in FogFroxelParams.froxel_dims so shaders can map
between absolute indices and normalised volume UVs without recompiling.
