How it works

Shader type
spatial
Render modes
unshaded, cull_disabled, depth_test_disabled, depth_draw_never, skip_vertex_transform, fog_disabled
Parameters
screen_texture (sampler2D), vignette_color (vec4 = 0.02, 0, 0.04, 1), intensity (float = 0.75), radius (float = 0.55), softness (float = 0.45), roundness (float = 1), focus_x (float = 0.5), focus_y (float = 0.5)
Use it on
A MeshInstance3D with a 2 x 2 QuadMesh, `material.tres` as its material override and a large extra cull margin, as in `demo.tscn`.
Result
The scene with soft, very dark purple edges and a clear centre.

Limits to consider

A colour blend, not an exposure change: bright highlights at the edges are flattened toward the colour. 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.
