Underwater camera view
In your harnessGodot shaderMIT
Make the camera look underwater: wavy screen distortion, wavelength-dependent absorption by distance from the depth buffer (red fades first), a blue-green scattering colour, brighter light from above and a vignette.
What it takes and gives
- Shader type
- spatial
- Render modes
- unshaded, cull_disabled, depth_test_disabled, depth_draw_never, skip_vertex_transform, fog_disabled
- Parameters
- screen_texture (sampler2D), depth_texture (sampler2D), water_color (vec4 = 0.04, 0.28, 0.38, 1), absorption (float = 0.22), red_absorption (float = 3), distortion (float = 0.006), wave_frequency (float = 18), wave_speed (float = 1.5) and 2 more
- Use it on
- A MeshInstance3D with a 2 x 2 QuadMesh,
material.tresas its material override and a large extra cull margin, as indemo.tscn. - Result
- The scene tinted deep teal and fading into murk with distance, gently wavering.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified

Limits. Sky pixels are clamped to 200 metres of water. The wobble is screen-space and the same at all depths. No caustics or particles (see underwater_caustics for surface caustics). The pass reads Godot's screen texture after opaque geometry, so transparent objects drawn after it are not processed and its order among other transparent passes is not controlled.
