Functions

bed_water_depth

#

Water depth under the sea level from the game’s bed height map. Outside the mapped area (or with no map at all) the sample keeps the deep default, mirroring a full-depth capture texel.

fn bed_water_depth (
world_xz: vec2<f32>
) -> f32

blended_water_depth

#

The bed map is world-static, so Crest’s cascade blending for SeaFloorDepth collapses to one lookup; only the shallow-attenuation cap remains.

fn blended_water_depth (
world_xz: vec2<f32>
) -> f32

caustic_bed_radiance

#

Direct sunlight reaches the bed before Beer-Lambert mixing.

fn caustic_bed_radiance (
scene_colour: vec3<f32>
, 
world_xz: vec2<f32>

water_depth: f32
